A new Fe‐Pt alloy catalyst for the oxygen reduction reaction of PEMFCs was prepared using a chelating agent, EDTA‐Fe(III), as its non‐precious metal source. Characterization showed that while the conventional catalyst showed particle aggregation over 5 nm, the new catalyst had a uniform particle size and a larger surface area. This new catalyst showed a higher catalytic mass activity than a conventional alloy catalyst although the specific activities are in the same range.
