  • Publication number: 20170279143
    Abstract: In this fuel cell electrode catalyst layer, a catalyst is supported on a carrier comprising inorganic oxide particles. The fuel cell electrode catalyst layer is provided with a porous structure. When a mercury penetration method is used to measure the pore size distribution of the porous structure, a peak is observed in the range spanning from 0.005 ?m to 0.1 ?m inclusive, and a peak is also observed in the range spanning from over 0.1 ?m to not more than 1 ?m. When P1 represents the peak intensity in the range spanning from 0.005 ?m to 0.1 ?m inclusive, and P2 represents the peak intensity in the range spanning from over 0.1 ?m to not more than 1 ?m, the value of P2/P1 is 0.2-10 inclusive. It is preferable that the inorganic oxide be tin oxide.
