FUEL CELL STACK

摘要

There is a problem with conventional fuel cell stacks in that the parts count is increased in order to obtain a structure with which vibration of the laminate is controlled. A fuel cell stack (FS) is produced by forming a structure comprising a laminate (1) obtained from unit cells (FC) in the form of rectangular plates, end plates (2) disposed at both end faces of the laminate (2), and a pair of reinforcing plates (3) disposed at the first and third outer peripheral faces when the four faces parallel to the cell lamination direction of the laminate (1) circumferentially serve as the first through fourth outer peripheral faces, wherein the respective end plates (2) and reinforcing plates (3) are connected, each reinforcing plate (3) has a base plate part (3A) that covers the first or third outer peripheral face of the laminate (1), a pair of support parts (3B) that cover a portion of the second and fourth outer peripheral faces of the laminate (1), each support part (3B) supports the laminate (1) as a spring element, and the spring elements are attached in the direction of displacement of the laminate (1). As a result, the resonant frequency of the laminate is increased and vibration resistance is improved without increasing the parts count.
