摘要： Mesoporous carbon (10) has a connecting structure in which primary particles (12) made of carbon particles having primary pores with a primary pore diameter of less than 20 nm are connected. In the mesoporous carbon (10), the pore capacity of secondary pores (14) with secondary pore diameters within a range of 20 nm to 100 nm, which is measured by a mercury intrusion method, is 0.42 cm 3 /g or more and 1.34 cm 3 /g or less. In addition, the mesoporous carbon (10) has a linearity of 2.2 or more and 2.6 or less. An electrode catalyst for a fuel cell includes the mesoporous carbon (10) and catalyst particles supported in the primary pores in the mesoporous carbon (10). Furthermore, a catalyst layer includes the electrode catalyst for the fuel cell and a catalyst layer ionomer.

摘要： Mesoporous carbon has a beaded structure in which primary particles with mesopores are linked. In the mesoporous carbon, an average primary particle size is 7 nm or more and 300 nm or less, a pore diameter is 2 nm or more and 10 nm or less, an average thickness of pore walls is 3 nm or more and 15 nm or less, a pore volume is 0.2 mL/g or more and 3.0 mL/g or less, and a tap density is 0.03 g/cm 3 or more and 0.3 g/cm 3 or less. 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.
