[0002] A Mobile Integrated Energy Supply System (MIESS) is a system that integrates multiple energy supply methods, providing electricity, heat, and other forms of energy to mobile devices or temporary facilities. This type of system is typically designed for locations where traditional energy infrastructure is difficult to access, such as military operations, fieldwork, emergency rescue, and construction in remote areas. With technological advancements, MIESS is evolving towards greater intelligence, efficiency, and environmental friendliness.

[0058] The tail vent condenser 15 is connected to the tail vent pipeline of the fuel cell system 8, and the water tank 16 is connected to the tail vent condenser 15.

[0059] In this embodiment of the invention, since the only emission product of the fuel cell system 8 is water, and the outlet of the tailpipe is supersaturated water vapor, the water is pure and can be directly drunk or used as domestic water.

[0060] Another embodiment of this utility model provides a mobile integrated energy supply vehicle, based on the above-mentioned mobile integrated energy supply system, including a vehicle body and a mobile integrated energy supply system, wherein the vehicle body is a fuel cell range-extended hybrid electric vehicle.

[0061] Working principle: During use, the organic liquid hydrogen release unit 3 undergoes a dehydrogenation reaction at the reaction temperature to produce hydrogen gas. The hydrogen gas enters the hydrogen gas compression unit 4 to increase the gas pressure and is then supplied to the hydrogen gas control unit 4, which uniformly distributes the hydrogen gas supply.

[0062] After the organic liquid hydrogen storage and release system, fuel cell system 8, and vehicle electrical system are started, the mobile integrated energy supply system can start the mobile charging system, circulating cooling / heating system, and domestic water system according to different needs, thereby achieving the following functions:

[0063] 1) The hydrogen produced by the organic liquid hydrogen release unit 3 is supplied to the fuel cell system 8 to generate electricity through the hydrogen control unit 5. The electrical energy is transmitted to the vehicle power system, which supplies power to the mobile charging system. The charging gun is connected to external electric equipment to charge it. The energy storage converter 11 can also provide electricity for external use and the voltage is adjustable.

[0064] 2) For external cold water supply, the first three-way regulating valve 21 closes the hot-side flow of the heat exchanger 17, and the heat generated by the fuel cell system 8 is transferred to the air-cooled radiator 19 for absorption. The integrated heating and cooling air conditioner 14 switches to cooling mode, powered by the energy storage converter 11, and the second three-way regulating valve 20 closes the cold-side flow of the heat exchanger 17, allowing the integrated heating and cooling air conditioner 14 to operate, and the circulating water pump 18 to run. External circulating hot water flows through the circulating water pump 18, the second three-way regulating valve 20, and the integrated heating and cooling air conditioner 14 before being supplied to the external cold water.

[0065] 3) For external hot water supply, the first three-way regulating valve 21 opens the hot-side flow of the heat exchanger 17, and the heat generated by the fuel cell system 8 is transferred to the heat exchanger 17 for external heating. The integrated cooling and heating air conditioner 14 switches to heating mode, powered by the energy storage converter 11. The second three-way regulating valve 20 regulates the cold-side flow of the heat exchanger 17 and the flow of the integrated cooling and heating air conditioner 14, so that the integrated cooling and heating air conditioner 14 and the heat exchanger 17 are connected together, and the circulating water pump 18 runs. External circulating cold water flows through the circulating water pump 18, the second three-way regulating valve 20, the heat exchanger 17, and the integrated cooling and heating air conditioner 14 to supply external hot water.

[0066] 4) When the fuel cell system 8 is running, the only reaction product is water. The saturated water vapor in the tail is condensed into liquid water by the tail condenser 15 and stored in the water tank 16. This water is pure and potable and can be supplied to the outside as domestic water.

[0067] 5) External hydrogen supply: The organic liquid hydrogen storage system uses hydrogen-containing organic liquid to carry out dehydrogenation reaction and supply hydrogen to the hydrogen control unit 5. The hydrogen control unit 5 controls the hydrogen supply. The hydrogen dispenser 7 receives the hydrogen from the hydrogen control unit 5 and supplies hydrogen to external hydrogen energy equipment through the equipped hydrogen dispensing gun.

[0068] 6) Replenish hydrogen to the on-board hydrogen storage unit 6, connect to the external power grid, and provide power to the organic liquid hydrogen storage system. The organic liquid hydrogen storage system uses hydrogen-containing organic liquid to carry out dehydrogenation reaction and supply hydrogen to the hydrogen control unit 5. The hydrogen control unit 5 controls the hydrogen supply and transmits hydrogen to the on-board hydrogen storage unit 6 to replenish it.

[0069] When connected to the external power grid, the power battery 12 can be stored through the vehicle's power system without starting the fuel cell system 8. At this time, the organic liquid hydrogen storage system can be started separately. After the hydrogen storage system is started, it can replenish hydrogen to the on-board hydrogen storage unit 6.
