PURPOSE:To both improve a cooling effect and easily control temperature of a cell stack, by filling ceramic material powder in an air gap part between a cooler pipe and cooler holders and improving conduction of heat between the both pipe and holders. CONSTITUTION:Many single cells are built in layers to form a stack, to prevent a temperature rise due to heat generation by polarization of the cell, a cooler pipe 1 is arranged to about one place for several cells. This cooler pipe 1 is held to cooler holders 2 and built in a fuel cell stack 3. Silicon carbide is filled in an air gap part 4 between said pipe 1 and the holders 2. In this way, conduction of heat can be improved capable of easily controlling temperature of the stack and improving a cooling effect. |
