In a polymer electrolyte fuel cell, the mesoporous carbon is used as a catalyst carrier for at least an air electrode catalyst layer. The mesoporous carbon can be obtained by impregnating mesoporous silica satisfying a predetermined condition with a carbon source, performing polymerization and carbonization, and removing a template.",
