Fuel cell

A fuel cell comprising:

• an electricity generating cell to contribute to electricity generation, comprising a membrane electrode assembly and comprising a separator having an oxidant gas flow path and a separator having a fuel gas flow path sandwiching the membrane electrode assembly;
• a non-electricity generating cell not to contribute to electricity generation, comprising no membrane electrode assembly;
• and
• a stack in which the electricity generating cell and the non-electricity generating cell are stacked;
• wherein the non-electricity generating cell is stacked on the end of the stacking direction of a plurality of the electricity generating cells, and comprises a laminated structure in which a first separator, a heat insulating member, a second separator, a third separator and a terminal are laminated in this order from the electricity generating cell side,
• the heat insulating member is sandwiched by the first separator and the second separator to reduce the heat release from the electricity generating cells,
• an impurity removal flow path is formed between the second separator and the third separator, and the impurities contained in a fluid supplied to the stack are removed by the impurity removal flow path, and
• the terminal collects the electricity generated in the electricity generating cells.
