Patent ID: 8076041

Claim:
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.
