Abstract:
1. A fuel cell comprising a pair of separators and electrolyte electrode assemblies interposed between said separators, said electrolyte electrode assemblies each including an anode, a cathode, and an electrolyte interposed between said anode and said cathode, wherein each of said separators includes a first plate and a second plate stacked together in a stacking direction; a fuel gas channel for supplying a fuel gas to said anode, and an oxygen-containing gas channel for supplying an oxygen-containing gas to said cathode are formed between said first and second plates; a fuel gas supply hole extends through a center of a central region of said separators for supplying said fuel gas in said stacking direction; discharge passages are formed around said fuel gas supply hole, and extend through said central region of said separators for discharging said fuel gas and said oxygen-containing gas after reaction as an exhaust gas in said stacking direction; and a fuel gas distribution passage extends between said discharge passages along a surface of said separator, perpendicularly to said stacking direction for connecting said fuel gas supply hole and said fuel gas channel.
