Abstract：
 This invention relates to an adaptive method for fastening a fuel battery stack characterizing that a pull-rod passes through the internal part of a fuel battery stack to fasten the stack and the end plates at both ends closely, in which, the pull-rod is composed of two rods of different materials fixedly connected, the length of the rod meets the following relation: L1 is the length of the rod of one material, the thermal expansion coefficient of the rod is: alpha1, in which, L is the distance between the two end plates, alpha is the thermal expansion coefficient of the rod, L2 is the length of a rod of another material, the thermal expansion coefficient is alpha2. This invented battery stack can be available in the vibration environment and keeps its internal stress under different temperatures.
