摘要: A fuel cell includes a separator having a circular disk. On one surface of the circular disk, a fuel gas channel is provided for supplying a fuel gas to an anode, and on the other surface of the circular disk, an oxygen-containing gas channel is provided for supplying air to a cathode. The fuel gas channel has an end point at an outer circumferential end of the anode. A fuel gas discharge channel is connected to an end point of the fuel gas channel, such that the consumed fuel gas is emitted to an oxygen-containing gas supply unit, from a position spaced outwardly from the outer circumference of an electrolyte electrode assembly.

摘要: A separator includes a plurality of first and second sandwiching sections, a plurality of first bridges connected thereto, and first and second fuel gas supply units integrally connected to the first bridges. Electrolyte electrode assemblies are sandwiched between the first and second sandwiching sections. A fuel gas supply channel is formed in each of the first bridges. A fuel gas supply passage extends through the first and second fuel gas supply units in a stacking direction. A pressure loss generator mechanism is provided in the fuel gas supply channel. The pressure loss generator mechanism generates a pressure loss over the entire fuel gas supply channel for distributing a fuel gas equally to each of the electrolyte electrode assemblies.
