Insulating plate for hydrogen fuel cell stack

An insulating plate for a hydrogen fuel cell stack belongs to the technical field of hydrogen fuel cells and comprises an insulating plate body mounted between a collector plate and a gas distribution plate, and a plurality of dispersion areas communicated with a plurality of reaction through holes in the gas distribution plate are arranged on the insulating plate body along the circumferential direction of the insulating plate body. The fuel cell stack has the beneficial effects that loops of air, hydrogen and water can be independent from one another, the running stability of the fuel cell stack is ensured, cooling water is dispersed, and the cooling effect of the fuel cell stack is good. 一种氢燃料电池电堆用绝缘板，属于氢燃料电池技术领域，该氢燃料电池电堆用绝缘板，包括安装在集流板和配气板之间的绝缘板本体，所述绝缘板本体沿其周向设置有与配气板上的多个反应通孔相通连的多个分散区，每个分散区通过密封圈与所述集流板和配气板密封相连，本发明的有益效果是，本发明可使空气、氢气、水的各回路间彼此独立，保证了电堆运行的稳定性，而且冷却水分散，电堆的冷却效果好。
