The invention discloses a hydrogen supply system, a fuel cell engine and a vehicle, which relate to the technical field of fuel cell vehicles. The hydrogen supply system comprises a hydrogen supply pipeline, ahydrogen circulating pipeline and an exhaust valve, wherein thehydrogen supply pipeline is provided with a hydrogen heater and an injection ejector, a gas inlet of the hydrogen heater is configured to be communicated with a hydrogen supply source, a gas outlet of the hydrogen heater is communicated with an inlet of the injection ejector, and an outlet of the injection ejector is configured to be communicated with an anode inlet of an electric pile; the inlet end and the outlet end of the hydrogen circulating pipeline are configured to be respectively communicated with the anode outletof the electric pile and the inlet of the injection ejector; one end of the exhaust valve is communicated with the hydrogen circulating pipeline, and the other end of the exhaust valve is communicated with the outside of the hydrogen supply system. When the hydrogen supply system supplies hydrogen to the electric pile, the working requirements of the fuel cell engine under all working conditionscan be met, the power consumption is low, the hydrogen supply quality can be ensured in the long-term use process, and the reaction efficiency of the galvanic pile is ensured.
