Purpose – The purpose of this paper is to show how technical-economical cost modeling can help in steering research and development to target key production cost elements of new products based on emerging technologies. Design/methodology/approach – The authors demonstrate the development and use of a technical-economic cost model (TCM) of the proton exchange membrane (PEM) in fuel cells to steer research to produce more economical and reliable products. A TCM is developed to depict how the production cost per unit varies depending on the different fabrication methods, production rate limitations, material selection, labor distribution, energy consumption, financial parameters and the target production volume. By using such an approach in the design, research time and resources can be saved by prioritizing R&D and production scale-up options at an early stage. Findings – The results of this study show the importance of applying technical-economic cost model (TCM) techniques on early stage research projects to steer the development for resolving key problematic figures. As a case study, a cost analysis platform has been established to apply this technique by analyzing different manufacturing and R&D options for producing durable PEM fuel cells. The projected manufacturing cost of the PEM is found to be lower than previously estimated and the enhanced durability does not significantly impact this production cost. Originality/value – Production is an important factor in informing NPD targets and R&D direction. And yet it is difficult to estimate scaled up production cost for prototype products and components in the R&D lab. Technical-economic cost models (TCM) are a tool to assist decision-making in technology portfolio management and NPD.

Purpose The purpose of this paper is to investigate the effects of hydrogen humidity on the performance of air-breathing proton exchange membrane (PEM) fuel cells. Design/methodology/approach An efficient mathematical model for air-breathing PEM fuel cells has been built in MATLAB. The sensitivity of the fuel cell performance to the heat transfer coefficient is investigated first. The effect of hydrogen humidity is also studied. In addition, under different hydrogen humidities, the most appropriate thickness of the gas diffusion layer (GDL) is investigated. Findings The heat transfer coefficient dictates the performance limiting mode of the air-breathing PEM fuel cell, the modelled air-breathing fuel cell is limited by the dry-out of the membrane at high current densities. The performance of the fuel cell is mainly influenced by the hydrogen humidity. Besides, an optimal cathode GDL and relatively thinner anode GDL are favoured to achieve a good performance of the fuel cell. Practical implications The current study improves the understanding of the effect of the hydrogen humidity in air-breathing fuel cells and this new model can be used to investigate different component properties in real designs. Originality/value The hydrogen relative humidity and the GDL thickness can be controlled to improve the performance of air-breathing fuel cells.

Purpose Despite the increased recognition and emphasis on corporate social responsibility (CSR) as a topic and highly formalised CSR control systems, numerous well-publicised problems and scandals often involving multinational enterprises (MNEs) continue to emerge. These companies are mostly extrinsically motivated in CSR. They operate with highly formalised CSR systems that, in many cases, miss the prevention of anti-social and illegal behaviour. This might reflect the failure of extrinsic CSR to integrate the ethical dimension and/or the failure of intrinsic CSR to formalise and thus benefit from economies of scale. Currently, the conviction is growing that if CSR is to have a meaningful impact, it should be a matter of intrinsic motives, morale and ethical values rather than a formalised management tool. This research aims to focus on a sample of small and large companies in Switzerland, aiming at a comparison of key motives for CSR related to actual CSR implementation, performance and company size. Design/methodology/approach The study examined two groups: seven owner-managers of small- and medium-sized enterprises (SMEs) and seven managers of MNEs. Each group met for two focus group discussions that were qualitatively and visually analysed using MAXQDA. Findings The results show that CSR implementation in the examined Swiss SMEs is more related to moral commitment than to profit maximisation. These companies are often driven by soft assets, such as networks, by the nexus of mission and value set; by a system of initiatives and integrated behaviour; by proximity and informal, flat organisational structures; by the aspiration and ambition of craftsmanship or excellent service (instead of profit); by community involvement; by recruiting from the local community; by the willingness to grow slowly and steadily; by the avoidance of atomic markets; and finally, by the mental set up and sociological tradition of the stewardship concept. This contrasts with the extrinsically motivated approach of the MNEs under research. While MNEs follow their approach of “ethics for the firm that must pay”, the findings here identified potential transition cases of “ethics in the firm” and “ethics of the firm” within Swiss SMEs. This is consistent with others, resembling the need of this dichotomy to be revised. Research limitations/implications The cross-sectorial approach limits the degree to which motives can clearly be attributed to actual CSR performance or company size. Practical implications The results imply that policymakers, public institutions, scientific community, etc. should be careful when establishing systems that favour financial returns from CSR engagement, because, first, other research showed that a behaviour attributed to extrinsic motives is mostly perceived as dishonest and misleading, for instance, consumers. Second, extrinsic motivation might crowd out morale and paying lead actors for behaving altruistically or philanthropically might decline their intrinsic motivation. Notably, the crowding out of intrinsic motivation by extrinsic incentives is a phenomenon well-researched not only in regard to CSR but in various other areas linked to human behaviour. This has important implications for nearly every business operation, especially for mergers and acquisitions, as well as for the growth of businesses. Social implications It seems unsuitable to support social goods in intrinsic CSR by the implementation of a system of financial incentives (or consequences). Thus, an economic cost-benefit is inappropriate where CSR needs an ethical stand. The difference between extrinsic and intrinsic CSR is very difficult to bridge – both have powerful incentives and drivers preventing a potential cross-over. Originality/value In sum, this study showed that CSR is meaningful and justifiable even if it is not profitable in the first place or implemented in and managed through formalised systems. This leads to two conclusions: first, care should be taken when emphasising the extrinsic approach in relation to social goods and second, the cost of a possible mismatch in a climate of ethical principles might be substantial for societies’ moral inclination.

Purpose Since the market penetrations of service robots are only successful to a limited types of services, the purpose of the paper is to look into the reasons why the market penetrations are lagged from both technical and nontechnical perspectives. Automatic robotic recharging services, especially robotic refueling systems, are used as the case study for the investigation. Design/methodology/approach This paper surveyed the relevant technologies and products and conducted the feasibility study and risk management for new development of automated robotic refueling systems. This paper developed a cost model for the evaluation of robotic refueling systems. Findings There are no major technical barriers that exist for the development of robotic refueling systems, but two main risks of developing new robotic refueling systems are interference of existing patents and the extreme effort to further reduce the development cost of automated refueling systems. The recommendations have been made to new developers of service robots. Research limitations/implications The suggestions are made for further development on service robots, in general; however, this paper does not cover the physical development of service robots. Practical implications This study was actually conducted for a client company who has a strong interest in developing new products for automatic robotic refueling systems. The reported work has great significance for new comers in this area to understand the state of the art, technological challenges and some potential risks in the field. Originality/value To the best of authors’ knowledge, it will be the first academic paper to summarize the research and development effort on automatic recharging business. The targeted field is very typical in promoting robots in services. Even robotic refueling was proposed at very early stage of robotic application, the market penetration of refueling robots the market penetration is very limited, not because the technology readiness but some other factors. This work has its significance to identify technical and nontechnical challenges to promote robots in services.

Purpose The purpose of this paper is to investigate the thermal performance of the cooling plates with conventional straight channel and wavy channel designs. Design/methodology/approach A three-dimensional model involving coupled fluid flow and heat transfer processes is developed to study the thermal performance of the cooling plates. The effects of wavelength and amplitude on the cooling performance are also studied. In addition, two novel wavy channels with varying wavelength are proposed and investigated. Findings The simulated results are compared in terms of pressure drop, average temperature, maximum surface temperature, temperature difference between the maximum temperature and minimum temperature and surface temperature uniformity index. It is concluded that the cooling performance is significantly improved by the wavy channel. Practical implications The current study can improve the understanding of transport characterization of the cooling plates with wavy channel design and provide guidelines for the design of cooling plates. Originality/value The design of cooling plates with wavy channels can be used in proton exchange membrane fuel cells to improve the cooling performance.

Both fuel cells and lithium-ion cells are chemical sources of electric energy. In either of these sources, energy is obtained from chemical reactions performed at the electrodes. However, different constructions of those cells causes that they are characterized by different, and in many cases opposite, properties. Their combination into a single hybrid power source can therefore lead to utilization of advantages of both of them and, at the same time, mutual elimination of their disadvantages. The article presents control assumptions, structure of control system and control algorithm of a hybrid portable electric energy source in an early stage of development – a technology demonstrator. Discussed technology demonstrator integrates PEM fuel cells with Li-ion secondary cells.
