Abstract
A fuel cell including an anode conductive layer, an anode catalyst layer, an electrolyte membrane, a cathode catalyst layer, a cathode conductive layer, and a cathode diffusion layer stacked in this order, in which the cathode diffusion layer has a fabric structure in which a water-swellable fiber and a non-water-swellable fiber are arranged. Preferably, in the fabric structure, the water-swellable fiber is arranged in either one of a warp and a weft. Preferably, gas permeability of the cathode diffusion layer increases as the water absorption amount of the water-swellable fiber increases.
