摘要： A fuel cell is formed by stacking first cell units and second cell units alternately. An inlet buffer and an outlet buffer are formed on a surface of a first metal separator of the first cell unit. Bosses are provided in the inlet buffer and the outlet buffer of the first metal separator. An inlet buffer and an outlet buffer are formed on a surface of the second metal separator of the first cell unit. Continuous guide ridges are formed in the inlet buffer and the outlet buffer of the second metal separator. The bosses and the continuous guide ridges are provided at positions overlapped with each other in the stacking direction.

摘要： There has been a problem that the cell units cannot bear the load exerted on the units while being stacked since a fuel cell stack including a refrigerant channel formed between cell units each having an even number of electrolyte/electrode structures (MEA) and metal separators which are alternated does not have any structure supporting the separators forming the refrigerant channel in a stacking direction. In order to solve the above problem, in each of a first power generating unit and a second power generating unit, projections formed at the buffer portions of the separators are disposed in the same positions in the stacking direction with the MEA interposed therebetween. Since between the first and second power generating units, the projections of the buffer portions are staggered, the projections of the first and second power generating units are thereby disposed in the same positions in the stacking direction.
摘要翻译：存在这样一个问题，即，由于包括在具有偶数个电解质/电极结构（MEA）的单电池单元和金属分离器之间形成的包括制冷剂通道的燃料电池堆叠，所以电池单元不能承受施加在单元上的负载，不具有在层叠方向上支撑形成制冷剂流路的分离器的任何结构。为了解决上述问题，在第一发电单元和第二发电单元中的每一个中，形成在隔板的缓冲部分的突起设置在层叠方向上的相同位置，并且MEA插入其间。由于在第一和第二发电单元之间，缓冲部分的突起交错，因此第一和第二发电单元的突起在堆叠方向上位于相同的位置。
