Title:
燃料電池電極用触媒層及びその製造方法
Document Type and Number:
Japanese Patent JP6654586
Kind Code:
B2
Abstract:
There are provided a catalyst layer for a fuel cell electrode and a method of producing the same. The catalyst layer for a fuel cell electrode includes a metal-supported catalyst including a carbon carrier and a metal catalyst supported on the carbon carrier and a fluororesin ionomer. A value obtained when a primary particle diameter of the carbon carrier measured with an SEM, a pH value of the metal-supported catalyst measured by a specific method, and a ratio between a weight of the fluororesin ionomer and a weight of the carbon carrier of the metal-supported catalyst are applied to a specific formula is a certain value or more.
