[0031] See also Figure 1The utility model provides a hydrolysis hydrogen production fuel cell power generation system for recycling water, comprising: a water storage tank 1 and a pump body 2, a heat exchanger 3, a hydrolysis hydrogen production reaction structure 4, a fuel cell 5, and an air blowing structure 6; the water storage tank 1 is connected to the inlet of the pump body 2, the outlet of the pump body 2 is connected to the hydrolysis hydrogen production reaction structure 4, a hydrogen production agent is arranged in the hydrolysis hydrogen production reaction structure 4, the hydrolysis hydrogen production reaction structure 4 is connected to the anode 51 of the fuel cell 5, the outlet of the air blowing structure 6 is connected to the cathode 52 of the fuel cell 5, the outlet of the cathode 52 of the fuel cell 5 is connected to the inlet of the heat exchanger 3, and the heat exchanger 3 is connected to the water storage tank 1.

[0032] The water tank 1 has an opening at the top, and the heat exchanger 3 is fixed on the top of the water tank 1, and the pipe outlet of the heat exchanger 3 is directly opposite to the opening at the top of the water tank 1; the inlet of the pump body 2 is connected to the bottom of the water tank 1, and the outlet of the pump body 2 is connected to the hydrolysis hydrogen production reaction structure 4, in which a hydrogen production agent is installed, and the opening at the top of the hydrolysis hydrogen production reaction structure 4 is connected to the anode 51 of the fuel cell 5; the outlet of the air blowing structure 6 is connected to the cathode 52 of the fuel cell 5, and the outlet of the cathode 52 of the fuel cell 5 is connected to the pipe inlet of the heat exchanger 3, and the air is blown through the heat exchanger 3 by a fan or natural convection to cool the tail gas of the cathode 52, and the water is condensed into liquid and then flows into the water tank 1 to be recycled.

[0033] Hydrogen is generated by hydrolysis reaction between water and hydrogen generating agent, and then introduced into fuel cell 5 to generate electricity. The heat exchanger 3 is used to cool the tail gas of cathode 52 of fuel cell 5, and the water in the tail gas of fuel cell 5 is recycled.

[0034] The water-recycling hydrogen production fuel cell power generation system utilizes the water in the water storage tank 1 to cool the tail gas of the cathode 52, condenses the water in the tail gas and recycles it, thereby reducing the amount of water that the system needs to carry. When the water-recycling hydrogen production fuel cell 5 power generation system is used in automobiles and aircraft, the cruising range of the automobiles and aircraft can be increased due to the reduction in the weight of the water carried by the system.

[0035] The heat exchanger 3 includes fins 31 and a heat exchange pipe 32 . The heat exchange pipe 32 runs through the fins 31 . The inlet of the heat exchange pipe 32 is connected to the cathode 52 of the fuel cell 5 , and the outlet of the heat exchange pipe 32 is connected to the water storage tank 1 .

[0036] The arrangement of the fins 31 and the heat exchange pipe 32 facilitates the delivery of the cathode exhaust gas 52 to the heat exchange pipe 32.
