PROBLEM TO BE SOLVED: To provide a fuel cell in which drainage of each flow passage groove is excellently secured, liquid connection can be suppressed as much as possible and a back receiving member of the flow passage groove can be deleted.SOLUTION: In a power generation cell 11, an electrolyte membrane-electrode structure 12 is held by a cathode-side separator 14 and an anode-side separator 16. The cathode-side separator 14 includes: an oxidant gas flow passage 30; and an oxidant gas discharge communication hole 18b which is communicated with the oxidant gas flow passage 30. In the bottoms of a plurality of outlet flow passage grooves 34b communicating the oxidant gas discharge communication hole 18b with the oxidant gas flow passage 30, recesses 36br are provided and outlet coupling flow passage grooves 36b are constituted by connecting each of the recesses 36br.SELECTED DRAWING: Figure 1 |
