Development of pressure electrolyser and fuel cell with polymer electrolyte

Abstract Recent research concerning hydrogen technology focusses on membrane technology. Small electrolysers and fuel cells with high power density are attractive for many different applications such as transportation and energy storage for solar systems or other renewable energy sources. In order to lay the foundations of widespread applicatication, cost reduction must be achieved and a simple and reliable system must be designed. Various membrane/electrode units have been prepared and the results of electrolysis and fuel cell operation experiments are presented.
