PLATE-LAMINATED TYPE FUEL CELL

摘要

Intended is to prevent such plastic deformation of a separator, as might otherwise be caused by the heat cycle of a fuel cell, thereby to prevent the breakage of a power generating cell. The power generating cell (5) and the separator (8) having reaction gas passages (11 and 12) are alternately laminated in plurality. In the outer peripheral portion of that laminate, there are formed a fuel gas manifold and an oxidizer gas manifold, which communicate in the laminating direction with the gas passages (11 and 12) of the separator (8). The laminate is weighted in the laminating direction. The separator (8) is equipped with an inter-connect portion (8a) having the power generating cell (5) arranged at the central portion, and a pair of arm portions (8b) extended from the edges of the inter-connect portion (8a) and connected at their individual ends (8c) to the fuel gas manifold and the oxidizer gas manifold. The arm portion (8b) is made so flexible as to be displaced in the laminating direction, and its deformation is kept within an elastic range for the heat cycle period.
