Long Storage

On the total combination of their power, electric, economic, operating and ecological characteristics fuel cells (FC) on the base of oxygen (air) - aluminum (AA) electrochemical system are one of the most effective fuel cells. On their power/mass performances they are worse only the oxygen-hydrogen FC and some types of FC with the lithium anode. It is easy to recharge AA FC by means of the mechanical replacement of the working components after their expenditure. AA FC storage period is not less then ten years without degradation of their characteristics. Thus it is a prospective current source with a repeated operation. It is distinguished by the high power performances, long storage period and ecological cleanness as during their exploitation, as during their producing and utilization of the waste FC and the products of the reactions. The authors developed fundamental researches of the processes which take place at the systems and assemblies of power plants (PP) with AA FC. These researches allowed to eliminate the basic defects of AA FC which blocked their practical application. Autonomous current sources on the AA FC base can be effectively applied for the different users power supply in the main supply absence conditions. The basic application fields: telecommunication systems, transport, rescue-emergency parties and so forth. We created the aluminum-air fuel cells power plants (PP) with the alkaline and salt electrolytes with the different additions and special developed anode alloys. They have the wide ranged capacities from the unites of W up to hundreds of kW.

Free Piston

The authors present a novel power supply for mobile robotic systems. A monopropellant (e.g., hydrogen peroxide) decomposes into high temperature gases, which drive a free piston hydraulic pump (FPHP). The elimination of fuel/oxidizer mixing allows the design of simple, lightweight systems capable of operation in oxygen free environments. A thermodynamic analysis has been performed, and an experimental FPHP has been built and tested. The prototype successfully pumped hydraulic fluid, although the flow rate was limited by the off-the-shelf components used.

Urban geoheritage is a phenomenon that is present in almost every city, but so far, only some cities use it as a tourist product. In May and June 2019, in order to create an urban geoheritage trail in Liberec, it was mapped in the wider city centre. Considering the vastness of the area, mapping was carried out by volunteers who were interested in the topic of popularization of geology but did not have the expertise of geological knowledge. This lack of expertise may seem to be a significant limiting factor, but in fact, it is a positive thing, as the knowledge of the mapping volunteer is at a similar (low) level to the future user of the educational trail. Thus, in the evaluation of geosites, the expert-layman barrier is eliminated and the benefit is the feedback of the future user. However, participatory research has its own specifics, which must be adapted to the methodology used. First, it is to ensure the homogeneity of the data that is collected by a large number of volunteers and which can be influenced by subjective influences. Furthermore, it is their professional value and practical application. Finally, yet importantly, the technical parameters of data that will be further processed in GIS. This paper describes the research methodology used and summarizes the experience with the use of participatory research for the purpose of mapping urban geoheritage in Liberec.
