The cold water produced by the chiller can effectively dissipate heat for the fuel cell system, the electrolyzed water hydrogen production system, and the solid-state hydrogen storage system.
[0028] As a preferred embodiment, the AC / DC converter 60 is connected to the commercial power supply.
[0029] By comprehensively applying a solid-state hydrogen storage system, an electrolytic water hydrogen production system, a fuel cell power generation system, etc., this application realizes uninterrupted power supply for the data center in terms of hydrogen energy, and also solves the cold start problem of fuel cells at low temperatures. When the mains power is cut off, the hydrogen energy UPS system of this application can directly supply power to the data center for backup, optimizes the thermal management system, greatly reduces the material cost of the hydrogen energy UPS system, and provides great possibilities for the commercial application of hydrogen energy UPS in the data center.
[0030] As a preferred embodiment, the fuel cell system 30 is connected to the data center 50 through a first electric control valve 31; the first electric control valve 31 is the heat flow coolant control valve of the fuel cell system 30.
[0031] As a preferred embodiment, the electrolytic water system 10 is connected to the data center 50 through a second electric control valve 11; the second electric control valve 11 is the heat flow coolant control valve of the electrolytic water system 10; the electrolytic water system 10 is a PEM electrolytic water hydrogen production system.

[0034] As a preferred embodiment, the electrolytic water system 10 is connected to the chiller 90 through a fifth electric control valve 12; the fifth electric control valve 12 is the cold flow coolant control valve of the electrolytic water system 10.

[0036] As a preferred embodiment, the data center 50 is connected to the chiller 90 through a heat exchanger 51; the heat exchanger 51 is a plate heat exchanger.
[0037] The working process of the hydrogen energy UPS system applicable to the data center adopting this application is as follows:
[0038] The working process of the hydrogen energy UPS system applicable to the data center in this application is divided into two modes: (1) normal power supply; (2) power failure of the mains power supply, resulting in power outage.
[0039] (1) The mains power supply is normal. The mains power is converted by the AC / DC converter and then supplied to the data center through the DC / AC converter. At this time, the data center operates normally, and the chiller exchanges heat for the data center through the heat exchanger. At this time, the first electric control valve is opened, and the fourth electric control valve is closed. The first electric control valve adjusts the appropriate opening to supply heat to the fuel cell system, so that the fuel cell system maintains at the set temperature; in the case of low ambient temperature, the fuel cell system can also utilize the excess heat of the data center to keep its own temperature at the set temperature. If the mains power suddenly fails, the fuel cell system can start quickly, enabling the data center to operate normally.
[0040] The hydrogen energy UPS system simultaneously monitors the SOC (State of Charge) of the solid-state hydrogen storage system. When the SOC drops to the first set value, the second electric control valve is opened, and the fifth electric control valve is closed. The temperature of the PEM hydrogen production system gradually rises to the set temperature; when the SOC drops to the second set value, the solid-state hydrogen storage system needs to be refueled; the sixth electric control valve is opened, and the third electric control valve is closed. The third electric control valve controls the cold water of the chiller to cool the solid-state hydrogen storage system. When the temperature drops to the appropriate temperature, the PEM hydrogen production system starts to hydrogenate the solid-state hydrogen storage system. When the PEM hydrogen production system operates stably, it needs to dissipate heat. At this time, the second electric control valve is closed, and the fifth electric control valve is opened to switch the cold and hot water circulation, and use the cold water of the chiller to cool the PEM hydrogen production system; when the solid-state hydrogen storage system is full of SOC, the PEM hydrogen production system stops working, the second electric control valve and the fifth electric control valve are closed, the sixth electric control valve is closed, and the third electric control valve is opened to maintain the solid-state hydrogen storage system at the set temperature to prevent the solid-state hydrogen storage from starting up unsuccessfully due to low temperature when the mains power fails.
[0041] (2) The mains power supply fails, resulting in power outage. The fuel cell system receives the power outage signal and starts quickly. In the first few seconds, the battery provides power to the data center. When the fuel cell system reaches the set power, the fuel cell system provides power; since the first electric control valve and the third electric control valve are opened, the fuel cell system and the solid-state hydrogen storage system always maintain at the appropriate temperature, so they can start quickly. After the fuel cell system starts successfully, the first electric control valve is closed, and the fourth electric control valve is opened to switch the cold and hot media, and use the cold flow medium to dissipate heat for the fuel cell system when the fuel cell system is running. The solid-state hydrogen storage system always uses the hot flow medium for temperature during fuel cell power generation, so that hydrogen can be released normally and supplied to the fuel cell system, thus ensuring the continuous operation of the data center when the mains power is disconnected.
[0042] After the mains power is restored, the fuel cell stops supplying power, and the data center is supplied by the mains power. The PEM hydrogen production system starts or stops according to the SOC of the solid-state hydrogen storage system.
