Title: CATALYST LAYER, GAS DIFFUSION ELECTRODE, MEMBRANE-CATALYST LAYER ASSEMBLY, MEMBRANE-ELECTRODE ASSEMBLY, FUEL CELL STACK, AND COMPOSITION FOR FORMING CATALYST LAYER
Abstract:
Provided is a catalyst layer which contains a core shell catalyst and exhibits excellent performance. The present invention relates to a catalyst layer of a gas diffusion electrode that is provided in a solid polymer fuel cell, and the present invention comprises: a core shell catalyst which contains a first carrier that is formed from a conductive carbon material and catalyst particles that are supported by the first carrier and have a core shell structure; a polymer electrolyte; and a second carrier that is formed from a conductive carbon material and does not support the catalyst particles. In addition, this catalyst layer is configured such that the conductive carbon material of the first carrier and the conductive carbon material of the second carrier are the same as each other.
