The invention relates to the technical field of fuel cells, in particular to a fuel cell end plate, a fuel cell and a vehicle, the surface of the fuel cell end plate is subjected to insulation treatment and/or the fuel cell end plate is embedded in an insulation plate; the surface of the fuel cell end plate is subjected to insulation treatment, so that the creepage distance between the electrode close to the front end plate and the fuel cell end plate can be increased; the end plate of the fuel cell is embedded in the insulating plate, so that the creepage distance between the electrode close to the rear end plate and the end plate of the fuel cell is increased; the creepage phenomenon between the end plate and the motor can be effectively avoided by increasing the creepage distance, so that higher power output of the fuel cell is realized; and the most direct advantage is that the insulating property of the electric pile is improved, so that the insulating property of the system is also improved, and finally, the service lives of the electric pile and the system are indirectly prolonged.

    本发明涉及燃料电池技术领域,具体涉及一种燃料电池端板、燃料电池以及车辆,所述燃料电池端板表面进行绝缘处理和/或将燃料电池端板嵌入在绝缘板内;本发明通过燃料电池端板表面进行绝缘处理可以增加靠前端板的电极与燃料电池端板之间的爬电距离;通过将燃料电池端板嵌入在绝缘板内增加了靠近后端板的电极与燃料电池端板之间的爬电距离;通过增加爬电距离,能够有效避免端板与电机之间的爬电现象,进而实现燃料电池更大功率的输出;提升燃料电池在工作情况下的可靠性,最直接的优点是提高电堆的绝缘性能,从而也就提高了系统的绝缘性能,最终间接的提高了电堆和系统使用寿命。
