Zusammenfassung

Solid acid compounds represent a highly promising class of materials as electrolyzer and fuel cell electrolytes due to their remarkably high proton conductivity at intermediate temperatures (100-400°C). Since early work demonstrated the viability of the solid acid compound CsH2PO4, as a fuel cell electrolyte very little work has been done in this field and it is considered wide open for investigation. At this time, the two key factors preventing a breakthrough of CsH2PO4 based fuel cells are 1. the limited phase stability of the compound due to dehydration and 2. the reactivity with no...
