Abstract
The present invention provides a method of preventing liquid fuel that has penetrated from an anode from reaching a cathode and of effectively utilizing a cathode catalyst, which provides a membrane electrode assembly for fuel cell having high output density. In a membrane electrode assembly for fuel cell including an anode formed of a catalyst and a solid polymer electrolyte, a cathode formed of a catalyst and a solid polymer electrolyte, and a solid polymer electrolyte membrane formed between the anode and the cathode, an intermediate layer is formed between the cathode and the electrolyte membrane.
