Collector plate of hydrogen fuel cell stack

A collector plate of a hydrogen fuel cell stack belongs to the technical field of hydrogen fuel cells and comprises a collector plate body mounted between an insulating plate and a bipolar plate, and the collector plate body is provided with a cooling liquid channel, an air channel and a hydrogen channel along the circumferential direction of the collector plate body. The current collector plate has the beneficial effects that loops of air, hydrogen and cooling liquid can be independent from one another, the running stability of a galvanic pile is ensured, and the cooling liquid is dispersed, so that the cooling effect of the galvanic pile and the current collector plate is good. 一种氢燃料电池电堆集流板，属于氢燃料电池技术领域，该氢燃料电池电堆集流板，包括安装在绝缘板与双极板之间的集流板本体，所述集流板本体沿其周向设置有冷却液通道、空气通道和氢气通道，所述集流板本体通过密封圈与所述绝缘板密封相连，本发明的有益效果是，可使空气、氢气、冷却液的各回路间彼此独立，保证了电堆运行的稳定性，而且冷却液分散，使电堆和集流板的冷却效果好。
