The embodiment of the invention discloses a cold start purging method, device and equipment for a fuel cell engine and a medium. The method comprises the following steps: if a stop instruction of a fuel cell of a target vehicle is detected, opening a first purging passage to purge the fuel cell of the target vehicle; when a fuel cell purging completion instruction is detected, the first purging passage is closed, and the actually measured environment temperature of the target vehicle is obtained; if the actually measured environment temperature is smaller than a preset temperature threshold value, a second purging passage is opened to purge a target valve body of the target vehicle; wherein the target valve body comprises a hydrogen discharging electromagnetic valve and a water discharging electromagnetic valve. According to the technical scheme, after normal purging of the engine is completed, the valve body is independently purged, moisture in the valve body can be fully removed, freezing is prevented, it is guaranteed that the engine can be normally started at the low temperature, meanwhile, the heating time and heating power consumption after the valve body is frozen are shortened, and the cold start time and the engine efficiency are improved.

    本发明实施例公开了一种燃料电池发动机的冷启动吹扫方法、装置、设备及介质。其中,该方法包括:若检测到目标车辆的燃料电池停机指令,开启第一吹扫通路对所述目标车辆的燃料电池进行吹扫;当检测到燃料电池吹扫完成指令时,关闭所述第一吹扫通路,获取所述目标车辆的实测环境温度;若所述实测环境温度小于预设温度阈值,开启第二吹扫通路对所述目标车辆的目标阀体进行吹扫;其中,所述目标阀体包括排氢电磁阀和排水电磁阀。本技术方案,在发动机正常吹扫完成后对阀体进行单独吹扫,能够充分去除阀体内水分防止冻结,保证发动机低温下可以正常启动,同时缩短阀体冻结后的加热时间和加热功耗,提高了冷启动时间和发动机效率。
