Specifically, a radiator and a power pump 46 may be disposed on the circulating water line 42, and the power pump 46 drives water in the circulating water line to circulate through the radiator, thereby finally releasing heat generated by the fuel cell 41 during operation.

In order to improve the energy utilization rate of the hydrogenation system, in some embodiments of the present application, the hydrogenation system may further include a heat storage device 60, and the heat storage device 60 is used for storing the heat generated by the electric energy generation device 40 and/or the heat generated by the hydrogen pressurization device 30. For example, the heat storage device 60 may store heat released from the circulation water line 42 or heat generated by the hydrogen pressurizing device 30 compressing hydrogen. For example, the heat storage device 60 may be a constant temperature water tank, a hot water tank, or the like, which can store hot water, and the hot water generated by the electric energy generation device 40 or the hydrogen pressurization device 30 is introduced into the constant temperature water tank or the hot water tank to collect and store heat.

The first heat exchange chamber 31 may be a closed chamber formed by wrapping the outside of the hydrogen pressurizing device 30.

As still another example, the heat exchanger 70 may be disposed outside the heat storage device 60, and water introduced into the heat storage device 60 is heated by the heat exchanger 70 to achieve heat collection.

The second heat exchange chamber 71 and the third heat exchange chamber 72 may be separated into two chambers by a single partition plate, and the heat exchanger 70 may be separated into baffling heat exchange chambers, such as a plate heat exchanger, by a plurality of heat exchange plates.
