The invention belongs to the technical field of vehicles, and discloses a fuel cell engine safety detection method, a vehicle and a storage medium which are used for detecting a fuel cell engine in operation. The fuel cell engine safety detection method comprises the steps that the hydrogen concentration, the smoke concentration, the CO concentration and the VOC concentration in a fuel cell box are detected; if the hydrogen concentration, the smoke concentration, the CO concentration and/or the VOC concentration are abnormal, fault type judgment is executed, and the judgment conditions of the fault type include that if the hydrogen concentration is larger than or equal to C12, it is judged that the hydrogen concentration is high; if the hydrogen concentration is greater than or equal to C1 and the smoke concentration is greater than or equal to C2, stack ablation is judged; if the hydrogen concentration is greater than or equal to C1 and the VOC concentration is greater than or equal to C4, judging that the stack leaks; if the hydrogen concentration is less than C12 and the CO concentration is greater than or equal to C3, judging that the wiring harness is smoldered; if the hydrogen concentration is smaller than C12 and the VOC concentration is larger than or equal to C4, it is judged that the cooling liquid leaks. The safety of the fuel cell engine is improved by detecting the interior of the fuel cell engine box body in all directions.

    本发明属于车辆技术领域,公开了一种燃料电池发动机安全探测方法、车辆及存储介质,用于检测运行中的燃料电池发动机。燃料电池发动机安全探测方法包括:检测燃料电池箱体内的氢气浓度、烟雾浓度、CO浓度以及VOC浓度;若氢气浓度、烟雾浓度、CO浓度和/或VOC浓度异常,执行故障类型判断,故障类型的判断条件包括:若氢气浓度≥C12时,则判断为氢气浓度高;若氢气浓度≥C1且烟雾浓度≥C2时,则判断为电堆烧蚀;若氢气浓度≥C1且VOC浓度≥C4时,则判断为电堆泄漏;若氢气浓度<C12且CO浓度≥C3时,则判断为线束阴燃;若氢气浓度<C12且VOC浓度≥C4时,则判断为冷却液泄漏。通过对燃料电池发动机箱体内进行全方位的检测,提升了燃料电池发动机的安全性。
