Estimating the term…
An object of the present invention is to optimize an anode catalyst layer such that high output performance can be achieved even under low-humidity conditions. In addition, another object of the present invention is to provide a polymer electrolyte fuel cell having such an anode catalyst layer. The following is obtained: an anode catalyst layer for a polymer electrolyte fuel cell, which comprises a carbon support on which a catalyst is carried and a hydrogen ion-conductive polyelectrolyte, and wherein the catalyst is carried by a carbon support for which the hydrophilic characteristic value specified based on a value representing the amount of adsorbed water vapor/the amount of adsorbed nitrogen is 0.02 or less, or the hydrophilic characteristic value for the catalyst-carrying carbon support is 0.30 or less.
