Fuel cell module

A fuel cell module comprising a fuel cell stack formed by stacking electrolyte electrode assemblies and separators alternately in a stacking direction, the electrolyte electrode assemblies each including an anode, a cathode, and an electrolyte interposed between the anode and the cathode, a fuel gas channel for supplying a fuel gas along an electrode surface of the anode being formed on one surface of the separator and an oxygen-containing gas channel for supplying an oxygen-containing gas along an electrode surface of the cathode being formed on the other surface of the separator,

• wherein the electrolyte electrode assembly and a first end separator are provided at one end of the fuel cell stack in the stacking direction, the first end separator being provided outside the electrolyte electrode assembly in the stacking direction, the first end separator being configured to limit supply of the fuel gas to the fuel gas channel and to allow supply of the oxygen-containing gas to the oxygen-containing gas channel;
• a dummy electrolyte electrode assembly and a second end separator are provided at another end of the fuel cell stack in the stacking direction, the second end separator being provided outside the dummy electrolyte electrode assembly in the stacking direction, the dummy electrolyte electrode assembly having a shape of the electrolyte electrode assembly, having electrical conductivity, but not having a power generation function,
• wherein the dummy electrolyte electrode assembly is a metal stack body formed by stacking a plurality of metal plates, including an electrically conductive metal plate, and a ceramic felt.
