摘　　要：采用等效刚度模型,以典型燃料电池大型电堆为研究对象,提出了电堆的最优封装力设计与分析方法,给出了燃料电池堆在各种可能工况下的最佳封装力取值范围与选取准则,并重点研究了系统温度变化对于封装力的苛刻要求,结合系统性能与可靠性设计,给出了系统在满足所有工况和性能要求下的最佳封装力可行域。编译了专用封装力设计分析程序。Using the equivalent stiffness model proposed by the authors, the design and analysis method of the optimal clamping force for a typical fuel cell stack was proposed. The allowable region and selecting regulation for the large stack under various possible conditions was given, especially under the possible temperature conditions. Finally, the selecting region available for the optimal clamping force considering the various working condition, the stack performance and structure reliability was given. A special analysis program was designed for the design and analysis of the optimal assembly force of large stacks.
