The system can reasonably utilize the tail gas of the hydrogen internal combustion engine, the brake resistor and the waste heat of the supercharger to heat the liquid hydrogen source, so that the hydrogen can be stably supplied without an additional heat source when a vehicle runs. The system can realize safe and large-scale vehicle-mounted hydrogen storage, and can improve the comprehensive energy utilization rate of vehicles by utilizing waste heat, and the relationship between each system and a heat exchange system is explained as follows:
the hydrogen supply system in the embodiment is used for supplying hydrogen to a hydrogen internal combustion power system, and the structure of the hydrogen supply system is shown in fig. 1, and the hydrogen supply system mainly comprises an oil storage tank, a reactor, a separator, a buffer tank and a supercharger which are sequentially connected; the hydrogen source is stored in the oil storage tank, flows into the reactor when hydrogen supply is needed, and generates hydrogen under the action of the catalyst when the reactor is heated to a set reaction temperature. And the mixture of the hydrogen and the dehydrogenated liquid hydrogen source flows into the separator for gas-liquid separation, the separated hydrogen enters the buffer tank, and the dehydrogenated liquid hydrogen source returns to the oil storage tank. The hydrogen is pressurized to the pressure required by the hydrogen internal combustion engine by the supercharger and is supplied to the hydrogen internal combustion power generation system.
It should be further noted that the set temperature of the reactor is set according to the temperature of hydrogen generated by the hydrogen source, for example: the hydrogen storage technology developed in Japan and based on the traditional organic materials such as toluene and the like has the dehydrogenation temperature of more than 300 ℃; the liquid organic conjugated molecule hydrogen storage material is developed in China, and the dehydrogenation temperature of the material is about 150 ℃; the specific set temperature of the reactor is determined according to the hydrogen material.

It should be further noted that the electric energy generated by the hydrogen internal combustion power system cannot directly supply power to the traction motors, and generally needs to be rectified and inverted to supply electric energy to one or more traction motors, and the traction motors receive the three-phase controllable electric energy from the inverter part of the converter, and convert the electric energy into mechanical energy to supply the mechanical energy to a gear box, a vehicle wheel set or other auxiliary loads.
Further, the heat exchange system disclosed in this embodiment is used for transferring waste heat of a hydrogen-burning internal combustion engine or a hydrogen gas turbine, a brake resistor, a supercharger and other devices of the hydrogen internal combustion power system to the hydrogen supply system; the structure of the heat exchange system is explained in detail as follows:

The tail gas of the internal combustion engine is discharged after heat exchange. The supercharger, the brake resistor and the power battery cooling medium flow into the heat exchanger through respective cooling circulation systems, and flow back to the respective cooling circulation systems after heat exchange.
Furthermore, when the heat generated by the hydrogen-burning internal combustion engine, the hydrogen gas turbine, the brake resistor and the supercharger is excessive and the hydrogen supply system cannot be used completely, the heat can be applied to other devices, such as an air-conditioning and heating system for supplying to a vehicle.

when the vehicle is started by a cold machine, the power battery provides electric energy for an electric heating system and a supercharger which are configured on the reactor. The reactor is heated to a specific temperature to discharge hydrogen, and the hydrogen is pressurized by the booster and is delivered to a hydrogen-burning internal combustion engine (or a hydrogen engine or a hydrogen gas turbine). When the generated hydrogen meets the fuel supply requirement of the hydrogen internal combustion engine, the hydrogen internal combustion engine (or the hydrogen engine or the hydrogen gas turbine) is ignited to output traction power outwards.

When the vehicle stops, the power generation system of the hydrogen-burning internal combustion engine (or the hydrogen engine or the hydrogen gas turbine) does not stop, the generated electric energy charges the power battery, and the tail gas conducts heat to the hydrogen supply system through the heat exchange system.
