摘要

A fuel cell was constructed using proton-conducting perovskite SrCe_(0.95)Yb_(0.05)O_(3-). The solid electrolyte was coated with symmetrical Pt electrodes using magnetron sputtering. The fuel cell was tested using methane and hydrogen under dry and wet (3% water saturation) conditions. This study has shown that hydrogen provided lower resistance in terms of electrode processes and hence a higher power output. Methane under dry conditions resulted in particularly poor performance as a result of slow decomposition to hydrogen and there was physical evidence of carbon deposition inside the fuel cell. The production of hydrogen took place much more readily under wet methane by reforming, and this was reflected in a performance approaching that of the hydrogen fuel.
