Novel dual-phase symmetrical electrode materials for protonic ceramic fuel cells

Protonic ceramic fuel cells (PCFCs) can use hydrogen and hydrocarbon fuels to generate electricity with good performance and anti-cooking resistance. Herein, a novel dual-phase perovskite oxide BaCe0.5Fe0.4Ni0.1O3-δ (BCFN) with BaCe0.5Fe0.5O3-δ (BCF) as one reference was synthesized, characterized and then evaluated as the symmetrical electrodes for PCFCs. Both BCF and BCFN can be self-assembled into an orthorhombic cerium-rich oxide phase and a...
