An MEA (15) is housed inside frames (13, 14). First and second gas flow path forming members (21, 22) are interposed between the anode layer (17) and the cathode layer (18) of the MEA (15) and the first and second separators (23, 24), which are secured by bonding to both the upper and lower surfaces of the frames (13,14). The gas flow path forming parts (21, 22) are formed from a lathe-cut metal (25) comprising thin sheet metal. A plurality of perforations having a prescribed shape is formed in a grid form and in a stepped form in the lathe-cut metal (25). Curved planar parts (29a) that contact the surfaces of gas diffusion layers (19, 20) are formed on rings (27), in which the respective perforations of the gas flow path forming parts (21, 22) are formed. |
