An electrode () for fuel cell comprises: a catalyst carrier () that is an electrically-conductive carrier () with a catalyst () supported thereon; a first electrolyte resin (); and a second electrolyte resin (). The first electrolyte resin has oxygen permeability of less than 2.2&#xd7;10mol/(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&#xd7;10mol/(m s Pa) in the environment having temperature of 80 degrees Celsius and relative humidity of 50%.
