Patent

CA 2622183

A general purpose of the present invention is to improve the ion conductivity of a catalyst layer used in a fuel cell. The catalyst layer includes a catalytic metal, a carbon particle, and an ion exchanger. The catalytic metal is carried on the carbon particle. The ion exchanger includes a first functional group capable of being adsorbed or bound to the catalytic metal, and a second functional group providing the ion conductivity. The ion exchanger is adsorbed or bound to the catalytic metal via the first functional group. The bond between the catalytic metal and the ion exchanger includes a covalent bond, a coordinate bond or an ion bond, etc.
