Abstract
An adhesive layer 3 is disposed between a carbon particle 2 and a catalyst substance 1 of a catalyst-supporting particle for a fuel cell containing the carbon particle 2 and the catalyst substance 1. Thereby, the catalyst-supporting particle for fuel cell can be obtained in which a contact resistance between the catalyst substance and the carbon particle supporting the same is lower, and the aggregation of the catalyst substance is suppressed. A catalyst electrode for a fuel cell and the fuel cell using the above particle have a higher output power and an excellent durability.
