Problems solved by technology

[0004] However, setting the hydrogen pressure to a fixed value cannot adjust the hydrogen pressure value according to the operating state of the vehicle engine. If the hydrogen pressure value is set to a small value, it cannot meet the demand for hydrogen when the vehicle engine is running at high power. If the hydrogen If the pressure value is set too high, hydrogen will be wasted when the vehicle engine is running at low power, and if the hydrogen pressure is set too high, it will seriously reduce the service life of the fuel cell stack

Abstract

The invention provides a vehicle-mounted fuel battery hydrogen control device. The vehicle-mounted fuel battery hydrogen control device comprises a hydrogen storage module, a fuel battery stack, a control module, a proportional valve and a first pressure sensor; the hydrogen storage module is connected with the fuel battery stack and used for storing hydrogen and outputting hydrogen to the fuel battery stack; the proportional valve is arranged between the hydrogen storage module and the fuel battery stack and connected with the control module, and is used for controlling the pressure value ofhydrogen output from the proportional valve; the first pressure sensor is arranged between the proportional valve and the fuel battery stack and connected with the control module, and is used for detecting the pressure value of hydrogen output from the proportional valve and sending the pressure value of hydrogen output from the proportional valve to the control module; and the control module is used for comparing the pressure value of hydrogen output fro the proportional valve with the preset pressure value to generate a first control signal, and sending the first control signal to the proportional valve so that the opening angle of the proportional valve can be adjusted. The vehicle-mounted fuel battery hydrogen control device achieves that the pressure value of hydrogen entering the fuel battery stack is dynamically adjusted.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a hydrogen control device for a vehicle-mounted fuel cell. Background technique [0002] With the development of clean energy, fuel cells have become a power supply method for more and more electronic products. Hydrogen fuel cells are one of them and can be used to power vehicles. [0003] A hydrogen fuel cell refers to a device that generates electrical energy through a chemical reaction between hydrogen and oxygen. In a vehicle system, in order to control the output electrical energy, it is necessary to control the hydrogen pressure input to the fuel cell stack. The existing vehicle-mounted fuel cell hydrogen control device Both use a two-stage pressure reducing valve to set the hydrogen pressure input to the fuel cell stack at a fixed value, and generate electricity to power the engine by inputting hydrogen at a fixed pressure. [0004] However, setting the hydrogen pressure to a fi...
