PROBLEM TO BE SOLVED: To solve problems in a usual tightening method of a high molecular electrolyte fuel cell in which the cell is tightly supported by fur tightening bolts of the same diameter using a tightening plate, such as being difficult to get stable function of the cell because of unevenness of a plane pressure given to an electrode, furthermore, when a cell stack of the fuel cell tighten by the usual method is used for a power source of an electric car, the cell stack receives strong vibration along with a running of the car. SOLUTION: A fuel cell is tightened by three tightening bolts of different diameters for defining a plane. |
