Abstract
An electrode catalyst layer of an electrochemical device is an electrode catalyst layer of an electrochemical device, the electrode catalyst layer including a mesoporous carbon; a catalyst metal supported at least in the mesoporous carbon; and an ionomer. Before supporting the catalyst metal, the mesoporous carbon has mesopores with a mode radius of 1 nm to 25 nm and a pore volume of 1.0 cm/g to 3.0 cm/g and has an average particle diameter of 200 nm or more.
