Abstract
An electrode (31c) for fuel cell comprises: a catalyst carrier (110) that is an electrically-conductive carrier (130) with a catalyst (120) supported thereon; a first electrolyte resin (141); and a second electrolyte resin (142). The first electrolyte resin has oxygen permeability of less than 2.2×10−14 mol/(m s Pa) in an environment having temperature of 80 degrees Celsius and relative humidity of 50%. The second electrolyte resin has oxygen permeability of not less than 2.2×10−14 mol/(m s Pa) in the environment having temperature of 80 degrees Celsius and relative humidity of 50%.
