Abstract

To provide electrode catalyst which has the catalyst activity and durability at a practically durable level and contributes to lowering of the cost in comparison with the conventional Pt/C catalyst. The electrode catalyst has a support and catalyst particles supported on the support. The catalyst particle has the core part, the first shell part formed on the core part, and the second shell part formed on the first shell part. The core part contains W compound including at least W carbide, the first shell part contains simple Pd, and the second shell part contains simple Pt.
