A composite cathode, consisting of Ba(Zr 0.1 Ce 0.7 Y 0.2 )O 3−δ (BZCY) and Sm 0.5 Sr 0.5 CoO 3−δ (SSC) , exhibits remarkable catalytic activity towards oxygen reduction, dramatically enhancing the performance of low‐temperature SOFCs based on an oxide proton conductor, as shown in the figure. The peak power densities represent the best performances ever reported for this type of SOFCs—a promising low‐cost SOFC system.
