Pre Treatment

Solid oxide fuel cells with ceria, ceria-Cu, and ceria-Rh anode were demonstrated to generate stable electric power with waste vegetable oil through direct oxidation of the fuel. The only pre-treatment to the fuel was a filtration to remove particulates. The performance of the fuel cell was stable over 100 hours for the waste vegetable oil without dilution. The generated power was up to 0.25 W/cm2 for ceria-Rh fuel cell. This compares favorably with previously studied hydrocarbon fuels including jet fuels and Pennsylvania crude oil.

Methanol Economy

This review presents methanol as a potential renewable alternative to fossil fuels in the fight against climate change. It explores the renewable ways of obtaining methanol and its use in efficient energy systems for a net zero-emission carbon cycle, with a special focus on fuel cells. It investigates the different parts of the carbon cycle from a methanol and fuel cell perspective. In recent years, the potential for a methanol economy has been shown and there has been significant technological advancement of its renewable production and utilization. Even though its full adoption will require further development, it can be produced from renewable electricity and biomass or CO2 capture and can be used in several industrial sectors, which make it an excellent liquid electrofuel for the transition to a sustainable economy. By converting CO2 into liquid fuels, the harmful effects of CO2 emissions from existing industries that still rely on fossil fuels are reduced. The methanol can then be used both in the energy sector and the chemical industry, and become an all-around substitute for petroleum. The scope of this review is to put together the different aspects of methanol as an energy carrier of the future, with particular focus on its renewable production and its use in high-temperature polymer electrolyte fuel cells (HT-PEMFCs) via methanol steam reforming.

As an environmentally friendly technology, the fuel cell is one of the alternative technologies that can replace fossil fuels. Various types of fuel cells are available in the market, including the solid oxide fuel cell (SOFC). The planar and tubular designs of SOFC are the leading designs mentioned in the literature. Several factors such as manufacturing cost, manufacturing process and production scale differentiate between the two main designs. Each cell component can be produced using a number of methods, two of which are the most common, namely dry pressing and screen printing techniques for the making of planar SOFC. This paper thus reviews several works that have utilized each of the fabricating methods mentioned. The processing steps, technical parameters, and results, such as the maximum power density of each method are discussed.

Density Values

The electroless deposition and galvanic displacement methods were used for the fabrication of cobalt–boron (CoB) catalysts modified with small amounts of platinum crystallites in the range of 9.8 to 14.4 μgPt cm–2. The prepared catalysts were studied as the anode materials for direct borohydride–hydrogen peroxide (NaBH4/H2O2) fuel cells at temperatures of 25–55°C. Polarization curves have been recorded with the aim to evaluate the fuel cell performance using the prepared CoB and that modified with Pt crystallites as the anode catalysts. For all catalysts (pure CoB and PtCoB) investigated, the peak power density values increase consecutively with the increment in temperature from 25°C up to 55°C. The values from 86–146 mV cm–2 and 146–234 mV cm–2 were determined for pure CoB and PtCoB catalysts, respectively. The highest specific peak power density of 21.5 kWgPt–1 was achieved at 55°C temperature when the PtCoB catalyst with the Pt loading of 9.8 μgPtcm–2 was employed as the anode catalyst in the NaBH4/H2O2 single fuel cell.

The Impact

Due to the emerging development in the energy industry, the demand for electricity consumption has sharply increased for each country. Therefore, a new recovery of energy resources is needed in consequence of the decreasing dependency on conventional energy resources, while sustaining energy security in the aspect of energy supply and climate change issues. The fuel cell is one of the most potential resources to be explored in order to overcome the constraints of the current energy generation. The aim of this paper is to discuss the entire cycle of the fuel cell system. It is starting from biogas production up to the recent studies related to life cycle assessment on fuel cell studies. Most of the researchers focused on the technical part of fuel cells; however, a comprehensive environmental assessment is essential to fully recognize the impact of fuel cells. Furthermore, this conceptual paper provided an idea on understanding the concept of fuel cell and referred to recently published articles related to life cycle assessment. Hopefully, this study can provide the guideline in determining the future energy for this country, in order to be less dependent on the current resources of energy supply.
