The invention relates to the technical field of vehicles, in particular to a fuel cell engine anode subsystem leakage detection method and device and a vehicle, and the method comprises the steps: judging whether a self-inspection request exists or not; if the self-inspection request exists, hydrogen supply operation is carried out on the galvanic pile, hydrogen supply to the galvanic pile is stopped when the hydrogen pressure in the galvanic pile reaches a preset pressure value, and the hydrogen pressure change value of the galvanic pile and the environmental hydrogen concentration are obtained within a preset duration; and generating a pipeline detection result and/or a galvanic pile detection result according to the hydrogen pressure change value and the environmental hydrogen concentration. Therefore, the problem that the hydrogen leakage position and the risk level cannot be actively predicted in the prior art is solved, and the safety of the vehicle is improved.

    本发明涉及车辆技术领域,特别涉及一种燃料电池发动机阳极子系统泄漏检测方法、装置及车辆,其中,方法包括:判断是否存在自检请求;若存在自检请求,则为电堆进行供氢操作,并在电堆内的氢气压力达到预设压力值时,停止为电堆供氢,并在预设时长内获取电堆的氢气压力变化值和环境氢气浓度;根据氢气压力变化值和环境氢气浓度生成管路检测结果和/或电堆检测结果。由此,解决了相关技术中无法主动预测氢气泄漏位置及风险等级的问题,提升了车辆的安全性。
