Electrode materials for solid oxide fuel cells with proton-conducting electrolyte based on CaZrO3

The work studies chemical stability and thermal compatibility of composite electrodes in contact with proton electrolyte based on calcium zirconate. Composite of electrolytes of CaZr0.95Sc0.05O3–δ and CaZr0.9Y0.1O3–δ with Fe, Ni, Cu, and Pd metals and also with the perovskite oxide of SrTi0.8Fe0.2O3–δ are considered. Temperature dependences of resistance of porous electrodes made of these materials are studied.
