摘要

A battery cathode, a composition for a catalyst layer of a battery cathode, and a battery, each achieves excellent performance while using a non-platinum catalyst. The battery cathode includes a catalyst layer, wherein the catalyst layer contains a non-platinum catalyst, has a thickness of 15 μm or more, and has a conductance per 1 cm2 of an electrode area of more than 100 S and less than 350 S.

說明書

Moreover, in each of Examples of the present invention, a surprising effect that the performance maintenance ratio of the fuel cell, that is, the durability of the fuel cell, was remarkably improved by achieving both an increase in supply efficiency of oxygen and an increase in supply efficiency of protons to the carbon catalyst contained in the catalyst layer of the battery cathode, was confirmed.
