Abstract

A carbon material for catalyst carrier use excellent in both durability and power generation performance under operating conditions at the time of low humidity, in particular both durability of a carbon material for catalyst carrier use with respect to repeated load fluctuations due to startup and shutdown and power generation performance under operating conditions at the time of low humidity, and a catalyst for solid-polymer fuel cell use prepared using the same etc. are provided. To solve this technical problem, according to one aspect of the present invention, there is provided a carbon material for catalyst carrier use satisfying the following (A) to (D):
