Abstract:
A fuel cell comprising:a plurality of laminated separators arranged in a laminated direction;a plurality of oxidizing gas chambers and a plurality of fuel gas chambers separated from one another by the separators;a pair of end plates each positioned at one side of the plurality of laminated separators with respect to the laminated direction;an oxidizing gas supplying port positioned in one of the end plates;an oxidizing gas exhaust port positioned in one of the end plates;a plurality of oxidizing gas intake holes provided in each separator, said plurality of oxidizing gas intake holes in each separator including one side intake hole connected to said oxidizing gas supplying port and forming together with the one side intake hole in other separators an oxidizing gas main path extending in the laminated direction of the separators along which is supplied oxidizing gas from the oxidizing gas supplying port, said plurality of oxidizing gas intake holes in each separator also including another side intake hole connected to a gas intake port that is in communication with one of said oxidizing gas chambers;a fuel gas intake hole provided in each separator to supply fuel gas along the laminated direction of the separators to one of the fuel gas chambers;an oxidizing gas exit hole provided in each separator and communicating with one of the oxidizing gas chambers and with the oxidizing gas exhaust port;a fuel gas exit hole provided in each separator and communicating with one of the fuel gas chambers through which fuel gas exits;at least one rectifying plate extending across at least either the fuel gas intake hole or one of the oxidizing gas intake holes in each separator to facilitate uniform distribution of gas.
