PROBLEM TO BE SOLVED: To provide a membrane/electrode assembly for solid polymer fuel cell, and a solid polymer fuel cell, in which the location accuracy of a lamination of a catalyst layer/a seal material/an anode catalyst layer/a cathod catalyst layer is excellent, adhesion of the catalyst layer and an electrolyte membrane is excellent, and durability and power generation performance are excellent, at a low cost.SOLUTION: A first alignment mark 13, a barrier 12 of a seal material, and an electrode catalyst layer 15 are formed on the surface of one of a set of substrates 11, and the surface of the substrate 11 is covered with an adhesive layer 17 composed of an electrolyte. A second alignment mark 14 located at a position in mirror image relation with the first alignment mark 13, a barrier 12 of a seal material, and an electrode catalyst layer 15 are formed on the surface of the other substrate 11, and the surface of the other substrate 11 is covered with an adhesive layer 17 composed of an electrolyte. The set of substrates 11 are disposed to face each other on the opposite sides of an electrolyte membrane 16, and then the first alignment mark 13 and the second alignment mark 14 are superimposed and bonded thus manufacturing a membrane/electrode assembly 5. |
