摘要： A decrease in voltage in a polymer electrolyte fuel cell comprising stack of unit cells caused by the temperature difference between the cells located at the ends and the other cells due to a differential in heat dissipation from end plates is prevented by controlling the cooling temperature of the cells closest to the end plates of the fuel cell without affecting the output voltage of the cells in the middle by not including a coolant flow channel in the conductive separator plate between at least one of the end plates and the unit cell located closest to the one of the end plates.

摘要： The invention relates to a separator plate for use in a fuel cell and to a fuel cell. The separator plate has: a passage groove group including a plurality of gas passage grooves 35 formed so as to extend in serpentine form; and a communicating groove 33 configured to provide fluid communication between adjacent portions of the gas passage grooves. Various separator plates have heretofore been disclosed in public by many documents and the blockage of the gas passage grooves caused by condensed water droplets formed therein is deemed to be properly prevented. However, the inventors think that those separator plates have a critical oversight in the behavior of a gas-liquid two phase fluid including a reaction gas and condensed water. That is, the condensed water is likely to concentrate in the vicinity of the gas passage grooves located in the downstream side of such separator plates and therefore these separator plates are liable to blockage. The invention intends to overcome the above problem by making the communicating groove 33 shallower than the gas passage grooves.
摘要翻译：本发明涉及一种用于燃料电池和燃料电池的隔板。隔板具有：通道槽组，包括形成为以蛇形形式延伸的多个气体通道槽35; 以及构造成在气体通道槽的相邻部分之间提供流体连通的连通槽33。迄今为止已经公开公开了各种分隔板，许多文件都认为可以适当地防止由其中形成的冷凝水滴引起的气体通道槽的堵塞。然而，发明人认为，这些隔板对包括反应气体和冷凝水的气液两相流体的行为具有严格的监督。也就是说，冷凝水可能集中在位于这种隔板的下游侧的气体通道槽附近，因此这些隔板容易堵塞。本发明旨在通过使连通槽33比气体通道凹槽更浅而克服上述问题。
