MESOPOROUS CARBON, ELECTRODE CATALYST FOR FUEL CELL, AND CATALYST LAYER

Mesoporous carbon includes a linked structure in which carbon particles are linked. The carbon particles have primary pores and are primary particles. An average entrance diameter of the primary pores is 2.0 nm or more and 3.0 nm or less. An average constriction diameter of the primary pores is 1.6...

Zusammenfassung:Mesoporous carbon includes a linked structure in which carbon particles are linked. The carbon particles have primary pores and are primary particles. An average entrance diameter of the primary pores is 2.0 nm or more and 3.0 nm or less. An average constriction diameter of the primary pores is 1.6 nm or more and 2.4 nm or less. An electrode catalyst for a fuel cell includes the mesoporous carbon and catalyst particles supported in the primary pores of the mesoporous carbon. A catalyst layer includes the electrode catalyst for a fuel cell and a catalyst layer ionomer.
