Abstract
The H2S-tolerance of SrFe0.75Mo0.25O3-? (SFM) electrodes has been investigated in symmetric proton ceramic fuel cells (PCFC) with BaZr0.8Ce0.1Y0.1O3-? (BZCY81) electrolyte. The ionic conductivity of the electrolyte under wet reducing conditions was found to be insignificantly affected in the presence of up to 5000ppm H2S. The fuel cell exhibited an OCV of about 0.9V at 700
