Abstract:
1. A fuel cell formed by stacking an electrolyte electrode assembly and separators horizontally, said electrolyte electrode assembly including a pair of electrodes and an electrolyte interposed between said electrodes, wherein a reactant gas flow field is formed between said electrolyte electrode assembly and one of separators sandwiching said electrolyte electrode assembly for supplying a reactant gas along a surface of said electrode, and a reactant gas passage connected to an outlet of said reactant gas flow field extends through said fuel cell in a stacking direction; said separator has a buffer between said reactant gas flow field and said reactant gas passage; said reactant gas flow field is oriented in a substantially horizontal direction, at the outlet of said reactant gas flow field along a surface of the separator, an end of said reactant gas flow field near said reactant gas passage is continuously extended outwardly beyond an end of an electrode catalyst layer of said electrolyte electrode assembly, and the end of said reactant gas flow field is inclined downwardly from the horizontal direction toward said buffer, and connected to said buffer.
