Abstract

The work studies chemical stability and thermal compatibility of composite electrodes in contact with proton electrolyte based on calcium zirconate. Composite of electrolytes of CaZr_0.95Sc_0.05O_3–δ and CaZr_0.9Y_0.1O_3–δ with Fe, Ni, Cu, and Pd metals and also with the perovskite oxide of SrTi_0.8Fe_0.2O_3–δ are considered. Temperature dependences of resistance of porous electrodes made of these materials are studied.
