Patent ID: 7258944

Claim:
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 a first area for providing said electrolyte electrode assemblies is formed between said separators; each of said separators includes a first plate and a second plate stacked together to form a second area between said first plate and said second plate; fuel gas channel, and an oxygen-containing gas channel are formed between the first plate and the second plate in the second area, the fuel gas channel and the oxygen-containing gas channel are separated by a partition, said partition including a ridge protruding from said first plate to contact said second plate; said fuel gas channel formed in one of said separators is connected to said first area through fuel gas inlets for supplying said fuel gas to anodes of said electrolyte electrode assemblies; and said oxygen-containing gas channel formed in the other of said separators is connected to said first area through oxygen-containing gas inlets for supplying said oxygen-containing gas to cathodes of said electrolyte electrode assemblies.
