A robust symmetrical electrode with layered perovskite structure for direct hydrocarbon solid oxide fuel cells: PrBa0.8Ca0.2Mn2O5+δ

A robust Ca doped PrBaMn₂O_5+δ with a layered perovskite shows not only good chemical and structural stability under reducing and oxidizing conditions but also remarkable electrochemical performance in hydrogen and hydrocarbon fuels for a symmetrical solid oxide fuel cells electrode.
