The fuel cell stack comprises a stacked body having stacked unit fuel cells, each being placed between separators, wherein each unit fuel cell has an anode, a cathode, and an electrolyte membrane placed therebetween; fastening plates provided at either end of the stacked body; an intermediate plate provided at an intermediate position of the stacked body; and bolt members inserted through the intermediate plate in the stacking direction in a manner such that the movement of the bolt members with respect to the intermediate plate in the direction perpendicular to the stacking direction is restricted. The stacked body is fastened together by fastening the fastening plates by using the bolt members.

摘要： The present invention is to provide a sealing member for a fuel cell which is able to keep surface pressure low, and to enhance sealing performance. The fuel cell includes an anode electrode and a cathode electrode which are sandwiched on both sides of a solid polymer electrolyte membrane, and an anode side separator and a cathode side separator which are then layered against both sides of this combination. Sealing members are installed into grooves on these separators. The cross section of each sealing member is formed with projecting portions extending in the widthwise direction of its groove on both sides of a semicircular shaped sealing member main body, and with a pair of cutaway portions in positions symmetrical about the center of a chord portion of the sealing member main body.
