The invention relates to a processing method of preventing frostbite and restarting of hydrogen electric pile, whose characteristic lies in the treating processes includes: When the electric pile turns off, the unsaturated fuel gas or the nitrogen, through the circle boast to clean the dissociate water; drying the MEA film module to keep the water content below the stipulated temperature which does not ice up; then the recycle gas through a wet exchanger to dry and the dried gas is continue used in the dry pile step; when restarting the electric pile, the recycle gas must heats then through the pile to elevate the temperature, then heats the fuel gas and the oxidant of the gas source, through the weting of the wet exchanger enters to the calefactive pile, enhances the wet step of the film module in the pile, starts the power output of the pile.

本发明涉及一种氢电堆的防冻和重新启动时的处理方法，其特征在于处理过程包括：电堆停机时，将水蒸气不饱和的燃料气体或氮气，通过循环吹扫除去电堆的游离水；干燥其中的MEA膜组件，使膜组件含水量降低到规定低温下不结冰的程度；而后再令循环气体通过一个湿交换机将循环气体干燥，以及被干燥后的循环气体继续用来干燥电堆的步骤；在电堆重新启动时，须将循环气体加热后通过电堆，使电堆升温，然后再将气源的燃料气及氧化剂加热，通过湿交换机加湿后进入已升温的电堆，提高电堆中膜组件的湿度的步骤，开始电堆的功率输出。
