ABSTRACT:
A heat insulating member is sandwiched by a first separator and a second separator. The heat insulating member functions as a heat insulating layer to prevent the temperature decrease of electricity generating cells. A first impurity removal flow path is formed in the space enclosed by the grooves on the surface of the second separator and a partition plate. A second impurity removal flow path is formed in the space enclosed by the grooves on the surface of a third separator and the partition plate. The impurity removal flow paths function as filters to remove the impurities contained in the reaction gases. A terminal functions as a current collecting layer to collect the electricity generated in the electricity generating cells. An end laminated body functions as a heat insulating layer to prevent the temperature decrease of the electricity generating cells, impurity removal layers to remove the impurities contained in the reaction gases and a current collecting layer to collect the electricity generated in the electricity generating cells.
