摘要： In a membrane electrode assembly of the present invention, at least one of a catalyst layer of an oxygen electrode and a catalyst layer of a fuel electrode includes a supported catalyst supporting a metal catalyst containing a platinum group element, a proton conductive polymer electrolyte, and at least one selected from (a) a complex-forming agent having a ligand that forms coordinate bonds with ions of the platinum group element and forms a complex, the ligand containing oxygen as a coordinating atom, (b) a complex of the platinum group element, a ligand of the complex containing oxygen as a coordinating atom, and (c) carbon that has a BET specific surface area of 100 m2/g or greater, satisfies at least one of (i) an R value of Raman spectrum of 0.5 or less and (ii) a lattice spacing d002 between (002) planes of 0.35 nm or less, and does not support the metal catalyst. With the use of the membrane electrode assembly of the present invention, it is possible to provide a polymer electrolyte fuel cell that has high durability and a long service life.
