CATALYST CARRIER FOR FUEL CELLS, CATALYST FOR FUEL CELLS, ELECTRODE CATALYST LAYER, AND FUEL CELL

Document Type and Number:

WIPO Patent Application WO/2023/218790

Kind Code:

A1

Abstract:

The present invention provides a catalyst carrier for fuel cells, the catalyst carrier being formed of carbon black, wherein: the specific surface area is 170 m2/g to 400 m2/g; and the ratio (S2/S1) of the peak area (S2)of the m/z 128 peak to the peak area (S1) of the m/z 57 peak as determined by programmed-temperature desorption gas analysis is less than 2.00.
