Abstract
A membrane electrode assembly includes solid polymer electrolyte membrane, an anode, and cathode. The cathode has a stacked body formed of a catalyst layer and a gas diffusion layer. The catalyst layer, which contains catalyst metal-supporting carbon particles and an ion conductor, further contains a mesoporous humidity control agent whose amount of water adsorption rises steeply as a relative humidity increases in a specific relative humidity region.
