A solid polymer fuel cell has a catalyst layer including a nanohorn aggregate as a catalyst carrier, catalyst metal supported on the catalyst carrier, and a polymer electrolyte coating the catalyst carrier. Voltage higher than the open circuit voltage of the solid polymer fuel cell is applied to the catalyst layer so as to increase triphasic interfaces at which the reaction gas reduced at the catalyst layer, the catalyst metal, and the polymer electrolyte meet.
Cellule électrochimique à polymère solide comportant une couche catalytique contenant un agrégat de nanocornet en tant que support de catalyseur, un métal catalytique supporté par le support de catalyseur, et un électrolyte polymère enveloppant le support de catalyseur. Une tension supérieure à la tension de circuit ouvert de la cellule électrochimique à polymère solide est appliquée à la couche catalytique de manière à augmenter les interfaces triphases au niveau desquelles le gaz de réaction réduit sur la couche catalytique, le métal catalytique et l'électrolyte polymère se rencontrent.
