The invention discloses a hydrogen leakage detection method and a target fuel cell engine. According to the scheme, the method comprises the steps that a TBOX judges whether a preset condition is met or not, if the preset condition is met, an FCU is awakened, and a first hydrogen leakage detection request is sent to the FCU; after the first hydrogen leakage detection request is received, the FCU controls a plurality of preset hydrogen concentration sensors to collect nearby hydrogen concentration values; the FCU determines a hydrogen concentration change trend corresponding to each preset hydrogen concentration sensor according to the plurality of hydrogen concentration values corresponding to each preset hydrogen concentration sensor; when the hydrogen concentration change trend corresponding to the preset hydrogen concentration sensor is that hydrogen leakage hidden danger exists, the FCU sends early warning information to the TBOX and enters a dormant state; and the TBOX sends early warning information to the target terminal equipment so as to prompt that the target fuel cell engine has the hydrogen leakage hidden danger and needs to be maintained in time.

    本公开公开了一种氢气泄露检测方法及目标燃料电池发动机。本公开提供的方案为:TBOX判断是否达到预设条件,若达到预设条件,则唤醒FCU,并向FCU发送第一氢气泄露检测请求;在接收到第一氢气泄露检测请求后,FCU控制多个预置氢浓度传感器采集附近氢气浓度值;FCU根据每个预置氢浓度传感器对应的多个氢气浓度值确定每个预置氢浓度传感器对应的氢气浓度变化趋势;当预置氢浓度传感器对应的氢气浓度变化趋势为存在氢气泄漏隐患时,FCU向TBOX发送预警信息,并进入休眠状态;TBOX向目标终端设备发送预警信息,以提示目标燃料电池发动机存在氢气泄漏隐患,需要及时进行维修。
