Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy, and in particular to a water-hydrogen production fuel cell power generation system and power generation equipment. Background Art

[0002] At present, the rapid development of science and technology has led to an increasing demand for energy. Fossil fuels are the main energy source but also the main pollutant. The harm to the environment is gradually increasing. Energy conservation and emission reduction have become an inevitable trend in social development. Therefore, energy conservation and emission reduction, improving energy utilization efficiency, and developing new energy have become the only way to achieve sustainable development.

[0003] As a high-energy fuel and clean secondary energy, hydrogen is used in various fields. Hydrogen has high calorific value and is pollution-free, so its use has received widespread attention. It can not only solve the problem of resource shortage, but also reduce environmental pollution.

[0004] However, hydrogen energy is limited by three technologies in the process of application: hydrogen production, storage and transportation. To resolve the above problems, one of the ways to achieve the effective and safe use of hydrogen energy is to achieve real-time hydrogen production and use. Hydrogen production by alloy hydrolysis is an on-site hydrogen production technology with high hydrogen storage density, but hydrogen production by hydrolysis requires carrying water as a raw material for hydrogen production, which increases the weight of the system. The wastewater discharged by fuel cell exhaust can be recycled to reduce the weight of the carried water.

[0005] For example, the hydrogen fuel cell system disclosed in CN212725392U directly passes the fuel cell tail gas into the water tank to recycle water, but this solution will increase the gas pressure of the fuel cell cathode flow channel and the power consumption of the fuel cell cathode blower. How to recycle the water content of the tail gas without increasing the resistance of the fuel cell cathode outlet has not yet been solved. Utility Model Content

[0006] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art of recycling the moisture in the tail gas without increasing the resistance at the cathode outlet of the fuel cell, thereby providing a hydrolysis hydrogen production fuel cell power generation system and power generation equipment.

[0007] In order to solve the above technical problems, the utility model provides a hydrolysis hydrogen production fuel cell power generation system, including a water storage structure and a water supply structure, a condensation structure, a hydrolysis hydrogen production reactor, a fuel cell, and an air blowing structure, wherein the water storage structure is connected to the inlet of the water supply structure, the condensation structure is connected to the water storage structure, the outlet of the water supply structure is connected to the tube side inlet of the condensation structure, the tube side outlet of the condensation structure is connected to the hydrolysis hydrogen production reactor, the hydrolysis hydrogen production reactor is connected to the anode of the fuel cell, the outlet of the air blowing structure is connected to the cathode of the fuel cell, and the cathode outlet of the fuel cell is connected to the shell side inlet of the condensation structure.

[0008] Furthermore, the condensation structure is arranged above the water storage structure, and the shell-side outlet of the condensation structure corresponds to the water storage structure.

[0009] Furthermore, the top opening of the hydrolysis hydrogen production reactor is communicated with the anode of the fuel cell.

[0010] Furthermore, a hydrogen-producing agent is provided in the hydrolysis hydrogen-producing reactor, and the hydrogen-producing agent is any one of magnesium or calcium, zinc, a magnesium alloy, a calcium alloy, and a zinc alloy.

[0011] Furthermore, the hydrogen-generating agent is any one of magnesium hydride, calcium hydride and zinc hydride.

[0012] Furthermore, the water storage structure is a water tank.

[0013] Furthermore, the condensation structure is a shell and tube condenser.

[0014] Furthermore, the water supply structure is a water pump or a peristaltic pump.

[0015] Furthermore, the blowing structure is a blower.

[0016] The utility model also provides a water-hydrogen-to-fuel cell power generation device, comprising the water-hydrogen-to-fuel cell power generation system.

[0017] The technical solution of the utility model has the following advantages:

[0018] The utility model provides a hydrogen production by hydrolysis fuel cell power generation system, comprising a water storage structure and a water delivery structure, a condensation structure, a hydrogen production by hydrolysis reactor, a fuel cell, and an air blast structure, wherein the water storage structure is connected to the inlet of the water delivery structure, the condensation structure is connected to the water storage structure, the outlet of the water delivery structure is communicated with the tube-side inlet of the condensation structure, the tube-side outlet of the condensation structure is communicated with the hydrogen production by hydrolysis reactor, the hydrogen production by hydrolysis reactor is communicated with the anode of the fuel cell, the outlet of the air blast structure is communicated with the cathode of the fuel cell, and the cathode outlet of the fuel cell is communicated with the shell-side inlet of the condensation structure.

[0019] The water storage structure has an opening at the top, and the condensation structure is fixed above the water tank, with the shell outlet of the condensation structure facing the opening at the top of the water tank. The water supply structure injects the water in the water storage structure into the tube side of the condensation structure, and then transports it to the hydrolysis hydrogen production reactor to react with the hydrogen production agent inside the hydrolysis hydrogen production reactor to produce hydrogen. Hydrogen is transported to the anode of the fuel cell to generate electricity. The air blowing structure sends air into the cathode of the fuel cell and transports the cathode tail gas to the shell side of the condensation structure. The tail gas is cooled by the water in the tube side of the condensation structure, and the water in the tail gas is condensed into liquid, which falls into the water storage structure from the shell side outlet of the condensation structure to be recycled, and the remaining gas is discharged to the outside.

[0020] The hydrolysis hydrogen fuel cell power generation system uses water in the water storage structure to cool the tail gas of the fuel cell cathode, condenses the water in the fuel cell tail gas for recycling, reduces the amount of water that the system needs to carry initially, and thus reduces the total weight of the system, that is, the water in the tail gas is recycled without increasing the resistance of the fuel cell cathode outlet. When the hydrolysis hydrogen fuel cell 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.
