PURPOSE:To improve durability by providing a pair of plates on both ends in the laminated direction of cells and arranging the guide of cooling fluid inside the electric conductive and heat conductive main frame. CONSTITUTION:Both of plural cells C of a fuel cell battery and cells C with gas passage constitutional materials Bs and fuel side gas passage constitutional materials Bf neighboting each other are connected together via the constitutional materials Bs, Bf in a conductive state. In such a state, both are arranged in a laminated condition, a cooling part R is provided between the neighboring cells C and cooling fluid is circulated between the cells C. The constitutional materials Bs are arranged to form oxygen gas passages S on the side of an oxygen pole 2, furnished with a conductive part and provided on the oxygen side. The constitutional materials Bf are arranged to form fuel gas passages (f) on the side of a fuel pole 3 and furnished with a conductive part. Plane part via which the cooling part R is opposed to almost all surfaces of the cell C are provided on both ends in the laminated direction of the cells C, the main frame R1 has electric conductivity and heat conductivity, and durability is improved when the main frame R1 is cooled through the guide R2 of the cooling fluid. |
