The ship engines in the shipping industry generate power through fuel combustion, and the fuel efficiency is low, and a large amount of air pollutants are emitted, mainly sulfur dioxide and nitrogen oxides, as well as a certain amount of particulate matter, hydrocarbons, carbon monoxide, and greenhouse gases such as carbon dioxide. These air pollutants have many adverse effects on human health and the environment, seriously affecting the realization of the major goal of carbon neutrality.

[0036] Compared with the hydrogen storage device for vehicles, a higher power level is required when applied to ships. Therefore, in some embodiments of the present invention, for example Figure 2 As shown, the first stack assembly 210 includes a plurality of first stack units 211 , the hydrogen inlets 231 of each of the first stack units 211 are interconnected, and the power supply output ends of each of the first stack units 211 are connected in parallel and to the power supply end group 300 .

[0037] In the first state, the hydrogen output port of the hydrogen storage module 100 is connected to the hydrogen input port 231 of each first fuel cell unit 211, so that hydrogen is supplied to each first fuel cell unit 211, and the electric energy generated by the reaction of each first fuel cell unit 211 is output in parallel, thereby increasing the output power of the entire first fuel cell assembly 210 to the ship power load 700, and in the second state, the connection between the hydrogen input port 231 of the first fuel cell unit 211 and the hydrogen output port of the hydrogen storage module 100 is cut off.

[0038] Similarly, in some embodiments of the present invention, such as Figure 3 As shown, the second stack assembly 220 includes a plurality of second stack units 221 , the hydrogen inlets 231 of each of the second stack units 221 are interconnected, and the power supply output ends of each of the second stack units 221 are connected in parallel and to the power supply end group 300 .

[0040] In some embodiments of the present invention, Figure 4 As shown, a reaction chamber is provided in the first stack unit 211, and the first stack unit 211 is also provided with an oxygen input port 232, a waste gas output port 233 and a produced water output port 234 respectively connected to the reaction chamber. The first stack unit 211 is provided with a membrane electrode member 240 in the reaction chamber, and the membrane electrode member 240 divides the reaction chamber into a first chamber 250 and a second chamber 260. The hydrogen input port 231 is connected to the first chamber 250, and the oxygen input port 232, the waste gas output port 233 and the produced water output port 234 are all connected to the second chamber 260. The membrane electrode member 240 is electrically connected to the power supply terminal group 300 to output electrical energy.

[0041] Hydrogen enters the first chamber 250 from the hydrogen input port 231, and the oxygen input port 232 can be connected to the outside or an oxygen source, and the air in the outside enters the second chamber 260 to provide an appropriate amount of oxygen.

[0042] The first fuel cell stack unit 211 is usually provided with a first catalytic component 251 in the first chamber 250 and a second catalytic component 261 in the second chamber 260.

[0043] The membrane electrode assembly 240 is a proton exchange membrane for hydrogen-oxygen reaction, and on both sides of the membrane electrode assembly 240, the pressure difference between the hydrogen located in the first chamber 250 and the oxygen located in the second chamber 260 can be controlled at 0.01-0.05Mpa. The membrane electrode assembly 240 cooperates with the first catalytic assembly 251 and the second catalytic assembly 261 to form hydrogen ions and oxygen ions. The hydrogen ions and oxygen ions react on the membrane electrode assembly to generate water, and the generated water is discharged from the water output port 234. Specifically, the water formed in the second chamber 260 is in a gas-liquid mixed state with the air.

[0044] Specifically, the second battery stack unit 221 may also adopt a structure similar to that of the first battery stack unit 211 .

[0045] In some embodiments of the present invention, the first stack unit 211 also includes a recovery pipe 270 and a check valve 280, the input end of the recovery pipe 270 is connected to the first chamber 250, the output end of the recovery pipe 270 is connected to the hydrogen input port 231, and the check valve 280 is used to limit the backflow of hydrogen from the output end of the recovery pipe 270 to the input end of the recovery pipe 270.

Since the first chamber 250 is blocked by the first catalytic component 251, a recovery output port 235 connected to the first chamber 250 is also provided in the first fuel cell unit 211. The recovery output port 235 and the hydrogen input port 231 are located at both ends of the first catalytic component 251. Hydrogen enters the first chamber 250 from the hydrogen input port 231. 50. Hydrogen passes through the first catalytic component 251. Under the catalytic effect of the first catalytic component 251, hydrogen ions pass through the membrane electrode 240 to react with oxygen. At this time, the hydrogen consumption plus the air resistance of the first chamber 250, therefore, the air pressure of the recovery output port 235 will be lower than the air pressure of the hydrogen input port 231. During the reaction process, the hydrogen in the first chamber 250 needs to be in a flowing state. Therefore, the recovery output port 235 needs to discharge hydrogen. In order to save resources, the recovery pipe group can recycle the hydrogen and circulate the discharged hydrogen to the hydrogen input port 231.

[0050] Since ships operate in the ocean, fresh water resources are relatively scarce, while the water generated by the reaction of the hydrogen storage energy supply device has fewer impurities and can be reused by the crew. Therefore, a water storage module 600 is provided, which is connected to the water output port 234 of each first battery stack unit 211 and the water output port 234 of each second battery stack unit 221. The water generated by the hydrogen-oxygen reaction can be discharged into the water storage module 600 and can be used by the user.

[0054] The gasified hydrogen fuel in the solid-state hydrogen storage component 110 can first enter the gaseous buffer component 120 for pre-storage. A buffer chamber is also provided in the gaseous buffer component 120. The gaseous buffer component 120 can first store the hydrogen provided by the solid-state hydrogen storage component 110, maintain a good output gas pressure, and then continuously provide it to the first fuel cell unit 211 or the second fuel cell unit 221, so that the power generation process can proceed continuously and stably.

[0055] Specifically, the solid hydrogen storage component 110 can be a solid hydrogen storage tank for storing solid hydrogen fuel, and metal powder can be placed inside to ensure that the solid hydrogen fuel has good stability, while the gaseous buffer component 120 can be a gaseous hydrogen storage tank with a buffer chamber inside.

In the first battery stack assembly 210, each first battery stack unit 211 is output in parallel.
