Abstract
PEM-electrolysers using the Cathode-Vapour-Feed (CVF) concept are currently considered to show the most promising capabilities for use within a Water Electrolysis Propulsion (WEP) system. However, only very limited data about the concept’s performance is publicly available so far. Therefore, such an electrolyser has been designed and tested at the European Space Agency (ESA) to identify any areas which require additional research. This paper describes the design of the developed electrolyser prototype and presents various test results, incl. polarization curves, transient behaviours during nominal operation as well as performance collapses at high temperatures.
