Embodiment 2

[0045] Such as figure 2 As shown, the specific structure of the Venturi tube 2 in this embodiment is: the Venturi tube 2 includes an inlet section 21 , a contraction section 22 , a throat 23 and a straight section 24 connected in sequence.

[0046] The diameter of the straight section 24 is the same as that of the throat 23. Specifically, the inlet section 21 is a short cylindrical section with a diameter of D; the shape of the constricted section 22 is a tapered tube with a cone angle of is 21°±2°; the throat 23 is a short straight pipe section with a diameter of about 1 / 3~1 / 4D, and the length is equal to the diameter of the pipe; the diameter of the straight section 24 is equal to the diameter of the circle of the throat 23 Tube.

[0047] By changing the diffusion section of the traditional Venturi tube 2 into a straight section 24, high-speed hydrogen with high kinetic energy can be obtained.

Embodiment 3

[0049] Such as figure 1 As shown, on the basis of Embodiment 2, this embodiment also includes two gas pressure stabilizing valves 7, one gas stabilizing valve 7 is installed between the wind power generator 32 and the fuel cell 4, and one gas stabilizing valve 7 is installed Between the power piston 51 and the fuel cell 4 .

[0050] Two gas stabilizing valves 7 keep the gas entering the fuel cell 4 at 1.5 atmospheres. In order to allow the fuel cell to absorb hydrogen more efficiently and increase the hydrogen utilization efficiency.

[0051] Concrete work process of the present invention is as follows:

[0052] S1. After the pressurized hydrogen flow in the hydrogen storage tank 1 enters the improved venturi tube 2, the hydrogen flow velocity increases and the pressure decreases;

[0053] S2. The hydrogen flow is divided into two parts, one part generates electricity through the wind power generator set 3, and the generated electric energy is stored in the storage battery ...

Description

technical field [0001] The present invention relates to a power generation system, in particular to a system based on hydrogen drive power generation. Background technique [0002] According to statistics, 60% of urban air pollution comes from motor vehicle exhaust emissions. Therefore, it is the general trend for new energy vehicles to gradually replace traditional fuel vehicles. Among the technical routes of various new energy vehicles, electric vehicles represented by hybrid vehicles, pure electric vehicles and fuel cell vehicles are generally considered to be the main direction for the transformation and development of future automotive energy and power systems, and have become the world's automotive powerhouse and major automotive industry. Manufacturer development focus. [0003] Compared with lithium battery electric vehicles, the most obvious advantage of using fuel cells is that it does not require a long charging process, and only needs a few minutes of hydrogenat...
