PROBLEM TO BE SOLVED: To provide a gas diffusion electrode having an outstanding electrode characteristic against oxygen reduction reaction, and a solid high polymer type fuel cell equipped with this, which can obtain high battery output. SOLUTION: The gas diffusion electrode has a catalyst layer containing a catalyst and fluoride containing ion-exchange resin, and a gas diffusion layer arranged adjoining with the catalyst layer. A high molecular compound, which has an oxygen penetration coefficient of 5×10<-11> [cm<3> (Normal).cm/cm<2> .s.Pa] or more, and does not have an ion exchange group substantially, is further contained in the catalyst layer. |
