Abstract

The long side of a rectangular first separator plate of a fuel cell is divided into n equal area smaller rectangular parts so that the long sides of the rectangular parts are not larger than 2.sup.1/2 and not smaller than 1/2.sup.1/2 the length of the short sides. Through holes pass through a stack of plates substantially at centers of the smaller rectangles. Bolts having an annular elastic member at one end pass through the through holes, and the stack is clamped together.
