Abstract
A fuel cell includes separators sandwiching electrolyte electrode assemblies. Each of the separators includes a fuel gas supply passage, four first bridges extending radially outwardly from the fuel gas supply section, and sandwiching sections connected to the first bridges. A fuel gas supply passage extends through the fuel gas supply section. Each of the sandwiching sections has a fuel gas channel and an oxygen-containing gas channel. The four electrolyte electrode assemblies are arranged concentrically around the fuel gas supply section. A fuel cell stack includes such fuel cells.
