摘要： A separator has a concavo-convex structure formed in mutually reversed shapes on two opposite sides thereof to define flow paths of different fluids on the respective two sides. The concavo-convex structure includes multiple first projections formed and protruded on one side of the two opposite sides and arranged at intervals having a preset regularity. The concavo-convex structure also includes multiple second projections formed and protruded on the other side of the two opposite sides in a specific area corresponding to an area for formation of the multiple first projections on the one side and arranged at intervals having a preset regularity. The concavo-convex structure further includes reinforcing elements protruded on the one side. Each of the reinforcing elements is formed as a convex in a specific shape of connecting multiple positions where the first projections are expected to be formed according to the preset regularity, while avoiding positions corresponding to the second projections formed on the other side. This arrangement effectively prevents a potential trouble caused by deformation of the separator due to a pressure difference between the flow pressures of the respective fluids flowing on the respective sides of the separator.
摘要翻译：分离器具有在其两个相对侧上以相互反转的形状形成的凹凸结构，以限定相应两侧上不同流体的流动路径。凹凸结构包括在两个相对侧的一侧上形成和突出的多个第一突起并以预定的规则间隔布置。凹凸结构还包括在对应于一侧上形成多个第一突起的区域的特定区域中在两个相对侧的另一侧上形成和突出的多个第二突起，并且以预定的规则间隔布置。凹凸结构还包括在一侧突出的增强元件。每个加强元件形成为具有预定规则性地预期形成第一突起的多个位置的特定形状的凸起，同时避免与形成在另一侧上的第二突起相对应的位置。这种布置有效地防止了由于在分离器的各个侧面上流动的各个流体的流动压力之间的压力差引起的分离器变形引起的潜在故障。

摘要： A stack structure of a fuel cell according to an aspect of the invention includes a plurality of separators of the fuel cell, and a protruding portion which has a tip portion that contacts a reference portion of an assembly jig during assembly of the fuel cell. Since the tip portion of the protruding portion contacts the reference portion of the assembly jig, an adhesive agent does not come out from the tip portion of the protruding portion. Therefore, it is possible to prevent positioning accuracy in stacking cells from being reduced. The reduction of the positioning accuracy is due to adhesion of the spreading adhesive agent to the reference portion of the assembly jig. In addition, it is possible to prevent a short-circuit from occurring. The occurrence of the short-circuit is due to deformation of the separator caused by making the separator contact the reference portion of the assembly jig.
摘要翻译：根据本发明的一个方面的燃料电池的堆叠结构包括燃料电池的多个分离器和在组装燃料电池期间具有接触组装夹具的基准部分的尖端部分的突出部分。由于突出部分的尖端部分接触组装夹具的参考部分，粘合剂不会从突出部分的顶端部分脱出。因此，可以防止堆积电池的定位精度降低。定位精度的降低是由于铺展粘合剂与组装夹具的参考部分的粘合。此外，可以防止发生短路。短路的发生是由于通过使分离器与组装夹具的基准部分接触引起的分离器的变形。

摘要： A separator for fuel cell includes a corrugated portion formed to have a corrugated cross section where a first groove that is concave to a first surface to form a flow path for a first fluid on the first surface and a second groove that is concave to a second surface opposite to the first surface to form a flow path for a second fluid on the second surface are arranged alternately and repeatedly. Each of the second grooves has at least one shallower groove section formed to have a less depth from the second surface than depth of a remaining groove section and provided to form a communication flow channel on the first surface side, which is arranged to communicate between two flow path spaces for the first fluid that are adjacent to each other across the shallower groove section.
