The invention provides a safety protection processing method of a fuel cell hydrogen system and a polyp, and is characterized in that the safety protection processing method comprises the following steps: collecting the temperature and pressure in a hydrogen bottle, and determining the hydrogen storage safety protection grade according to the current temperature and pressure in the hydrogen bottle; the hydrogen concentration is collected, and the hydrogen leakage safety protection level is determined according to the data of the current hydrogen concentration; signals of a collision sensor are collected, whether gas-electricity shutdown is carried out on the whole vehicle or not is determined according to the signal level of the collision sensor, and explosion and fire disasters caused by hydrogen leakage are prevented through design in the three aspects of a hydrogen storage safety strategy, a hydrogen leakage safety strategy and a collision and whole vehicle emergency safety strategy. And safe and normal operation of the fuel cell hydrogen system is ensured.

    本公开提供了一种燃料电池氢系统的安全防护处理方法及息肉,其特征在于,包括:采集氢瓶内的温度和压力,根据当前氢瓶内的温度和压力,确定储氢安全防护等级;采集氢气气浓度,根据当前氢气浓度的数据,确定氢气泄露安全防护等级;采集碰撞传感器的信号,根据碰撞传感器的信号电平高低,确定是否对整车进行燃电停机,通过储氢安全策略,氢泄露安全策略,碰撞及整车紧急安全策略三个方面进行的设计,防止因为氢气泄露而引起爆炸、火灾,保证了燃料电池氢系统的安全正常运行。
