Since oxygen supplied to the cathode plate can be obtained from air, electric power can be continuously supplied as long as oxygen (air) is continuously supplied to the cathode plate and hydrogen is continuously supplied to the anode plate. With the rapid development of hydrogen fuel cell technology, the market demand for fuel cell systems is also increasing, customers demand that the volumes and the masses of fuel cell systems be as small as possible, the functions be as diverse as possible, and the integration level of fuel cell systems be as high as possible, so that the development trend of the existing fuel cell systems is light weight and integration.
The hydrogen supply valve seat 100 is a main functional component of the fuel cell, and the function of the hydrogen supply valve seat 100 is to decompress the hydrogen gas supplied from the hydrogen supply component and deliver the hydrogen gas into the stack according to the flow rate and pressure required. The hydrogen supply valve seat 100 generally works at a higher ambient temperature, generates more heat when the pressure of the supply air flow is frequently switched, affects the operation of the valve set, and generates jolt vibration in the running process of the automobile, which affects the operation of the valve set. In the related art, the combined hydrogen supply valve seat 100 assembled by the cutting sleeve and the stainless steel pipe is generally adopted, because the combined hydrogen supply valve seat 100 has more parts, complex structure and easy omission in the installation process. In addition, due to the structure of the combined hydrogen supply valve seat 100, only a single proportional valve 300 can be installed, and when the power is greater than 100kw, the hydrogen pressure output by the combined hydrogen supply valve seat 100 is unstable, the hydrogen flow cannot be flexibly controlled by the arrangement of the single proportional valve 300, and the stability of the power generation of the hydrogen fuel cell is affected. How to simplify the structure of the hydrogen supply valve seat 100 and to ensure the stability of the power generation of the hydrogen fuel cell is a problem to be discussed and solved.
Based on the above, the integrated hydrogen supply valve seat can simplify the structure of the hydrogen supply valve seat 100, is convenient to process and install, can flexibly control the flow of hydrogen, and ensures the stability of power generation of the hydrogen fuel cell.

It should be noted that, the integrated hydrogen supply valve seat of the present application is internally provided with the hydrogen inlet flow channel 110, the first proportional valve flow channel 120, the second proportional valve flow channel 130 and the hydrogen output flow channel 140, one end of the hydrogen inlet flow channel 110 of the valve seat 100 is connected with an external hydrogen supply component, the other end of the hydrogen inlet flow channel 110 is respectively communicated with one end of the first proportional valve flow channel 120 and one end of the second proportional valve flow channel 130, the other end of the first proportional valve flow channel 120 and the other end of the second proportional valve flow channel 130 are respectively communicated with one end of the hydrogen output flow channel 140, the other end of the hydrogen output flow channel 140 is communicated with an external electric pile, when the external hydrogen supply component outputs hydrogen, the hydrogen inlet flow channel 110 communicated with the hydrogen supply component respectively transmits the hydrogen to the first proportional valve flow channel 120 and the second proportional valve flow channel 130, the hydrogen output flow channel 140 transmits the hydrogen to the communicated electric pile, when the hydrogen supply valve seat 100 is required to be used to control the hydrogen flow rate of the electric pile, the hydrogen supply valve seat is not required to be assembled in advance, the integrated hydrogen supply valve seat of the present application can be mounted between the integrated hydrogen supply valve seat and the hydrogen supply valve seat 100. In addition, in the present application, the proportional valve mounting ports 121 are formed at one side of the first proportional valve flow channel 120 and one side of the second proportional valve flow channel 130, so that the proportional valve 300 is mounted at one side of the first proportional valve flow channel 120 and one side of the second proportional valve flow channel 130, respectively.
According to one embodiment of the present application, the mounting members 160 are further disposed on both sides of the valve seat 100, and during the operation of the integrated hydrogen supply valve seat, the valve seat 100 is fixed on the substrate of the galvanic pile system through the mounting members 160 on both sides, and the hydrogen inlet flow passage 110 has a standard 1/2 pipe diameter, so that the pipe joint used in batch in the market can be matched, the pipe structure does not need to be redeveloped, and the versatility and interchangeability are improved.
According to another embodiment of the present application, the shutoff valve 200 can be installed on the valve seat 100 side by providing the shutoff valve installation opening 111 on the hydrogen inlet flow passage 110 side, and the proportional valve installation opening 121 is provided on both the first proportional valve flow passage 120 side and the second proportional valve 300 side, so that one proportional valve 300 is installed on each of the first proportional valve flow passage 120 side and the second proportional valve flow passage 130 side. Further, when the external hydrogen supply unit outputs hydrogen, the hydrogen inlet flow channel 110 transmits the hydrogen output by the hydrogen supply unit to the first proportional valve flow channel 120 and the second proportional valve flow channel 130 which are communicated with each other, at this time, the flow rate of the hydrogen transmitted by the hydrogen inlet channel can be controlled by adjusting the shut-off valve 200, the flow rate of the hydrogen transmitted by the hydrogen inlet channel into the first proportional valve 300 channel and the second proportional valve 300 channel can be further controlled, and in order to more precisely control the flow rate of the hydrogen transmitted by the hydrogen supply valve seat 100, the flow rate of the hydrogen of the first proportional valve flow channel 120 can be controlled by adjusting the first proportional valve 300, the flow rate of the hydrogen of the second proportional valve flow channel 130 can be controlled by adjusting the second proportional valve 300, and the flow rate of the hydrogen output to the electric pile can be further controlled, so as to realize more precise hydrogen pressure regulation. Specifically, when the hydrogen supply is not needed for the galvanic pile temporarily, the shut-off valve 200 of the hydrogen inlet flow channel 110 can be closed, and when the galvanic pile needs larger hydrogen supply, the shut-off valve 200 and the two proportional valves 300 can be simultaneously turned on, more specifically, the opening degrees of the shut-off valve 200 and the two proportional valves 300 can be properly adjusted by an operator according to specific requirements, so that the accurate control of the hydrogen flow rate is realized.
It should be noted that, in the hydrogen transfer process, the first proportional valve flow channel 120 and the second proportional valve flow channel 130 independently transfer hydrogen, the flow of the hydrogen transferred in the first proportional valve flow channel 120 and the flow of the hydrogen transferred in the second proportional valve flow channel 130 are not in common, the first proportional valve 300 cuts off the hydrogen in the first proportional valve flow channel 120 and does not affect the transfer of the hydrogen in the second proportional valve flow channel 130, and similarly, the second proportional valve 300 cuts off the hydrogen in the second proportional valve flow channel 130 and does not affect the transfer of the hydrogen in the first proportional valve flow channel 120.
