A fuel cell stack comprises an electrolyte electrode assembly, separators and terminal plates, stacked in a stacking direction. The electrode assembly includes an anode, a cathode, and an electrolyte. Each terminal plate has an electron conductive area made of a composite of porous metal and resin, and a passage area including a reactant gas passage or a coolant passage. The passage area is made of insulating resin. A fuel cell stack comprises an electrolyte electrode assembly (18), separators (14, 16) and terminal plates (24a), stacked in a stacking direction such that the electrolyte electrode assembly and the separators are stacked alternatively and the terminal plates are provided at opposite ends in the stacking direction of the fuel cell stack. The electrolyte electrode assembly includes an anode (38), a cathode (40), and an electrolyte (36) interposed between the anode and the cathode. Each terminal plate has an electron conductive area (50) made of a composite of porous metal (50a) and resin; and a passage area (52) made of insulating resin (51). The passage area includes at least one of a reactant gas passage (30a, 30b, 32a, 32b) and a coolant passage (34a, 34b). An independent claim is also included for a method of producing the fuel cell stack by stacking the electrolyte electrode assembly, the separators and the terminal plates in the stacking direction as above, comprising producing the electron conductive area using the composite of porous metal and resin; and producing the passage area using the insulating layer. |
