There is a problem with a conventional fuel cell stack 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 surfaces of the laminate (2), and a pair of reinforcing plates (3) disposed, when four surfaces parallel to the cell stacking direction of the laminate (1) are defined as a first to fourth outer peripheral surfaces in a circumferential direction, on the first and third outer peripheral surfaces, wherein the respective end plates (2) and reinforcing plates (3) are connected, each reinforcing plate (3) has a base plate (3A) covering covers the first or third outer peripheral surface of the laminate (1), a pair of holding portions (3B) that cover the second and fourth outer peripheral surfaces of the laminate (1) partly, each holding portion (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. |
