With the ultimate goal of simultaneously finding cost‐effective, more earth‐abundant, and high‐performance alternatives to commercial Pt/Pd‐based catalysts for electrocatalysis, this review article highlights advances in the use of perovskite metal oxides as both catalysts and catalyst supports towards the oxygen reduction reaction (ORR) and the methanol oxidation reaction (MOR) within a direct methanol fuel cell (DMFC) configuration. Specifically, perovskite metal oxides are promising as versatile functional replacements for conventional platinum‐group metals, in part because of their excellent ionic conductivity, overall resistance to corrosion, good proton‐transport properties, and potential for interesting acidic surface chemistry, all of which contribute to their high activity and reasonable stability, especially within an alkaline electrolytic environment.
