PROBLEM TO BE SOLVED: To perform welding substitutive for clamp and blaze welding by mutually opposing heat exchange surfaces of first/second corrosion resistant sheets, so as to define a flow passage for a liquid coolant, and electrically connecting the heat exchange surfaces via a conductive adhesive, including a corrosion resistant conductive particle and having specific resistance. SOLUTION: A conductive adhesive has resistance not more than about 1 Ω/cm. Plural lands 112 for defining plural grooves 114 in the upper part show a first corrosion resistant outside metallic sheet 110 provided on the upper part, and reaction gas is distributed by crossing the surface of a membrane electrode assembly connected to these by passing through these grooves. Similarly, a second corrosion resistant outside metallic sheet 116 has plural lands 118 for defining plural grooves 120, for distributing the reaction gas by crossing the membrane electrode assembly connected to these. The first/second corrosion resistant outside metallic sheets 110, 116 are separated by a waveform perforated metallic separate sheet 122, and are adhered with conductive joint 124. |
