PURPOSE:To provide a fuel battery free from risk of heat damage by introducing reaction gas to guide vanes of a reaction gas supplying device, allowing it to flow from the central part to the perimeter, thereby decreasing necessity for use of gas seal, and by using a glass seal at cell tack of the gas supplying device and unitary cell. CONSTITUTION:A space is bounded by the inner surface of a unitary cell, a reaction gas supplying device, and reaction gas lead-in pipes 4, 5, while another space is formed limited by the outside surface of the unitary cell and the reaction gas supplying device, and therein a glass seal 6 is provided either in the former space or in both. Thereby the reaction gas is introduces to guide vanes 19A, 19B of reaction gas supplying devices 7, 11 and flows from the central part to the perimeter. This decreases necessity for use of a gas seal between the unitary cell and the supplying devices 7, 11. Also the gas seals minimally needed at the central part or perimeters of the cell tack of the unitary cell and supplying devices 7, 11 consist of a glass seal, so that component members of the battery can make thermal expansion and contraction freely. |
