Fuel real-time monitoring and recycle device of fuel cell vehicle

Abstract

The invention provides a fuel real-time monitoring and recycle device of a fuel cell vehicle. The fuel real-time monitoring and recycle device comprises a main hydrogen supply pipeline and a hydrogen recycle pipeline, wherein the main hydrogen supply pipeline is used for adjusting pressure, temperature and humidity of hydrogen at an air outlet of the device by devices such as a temperature sensor, a heating device, a pressure regulation valve group and a pressure sensor, monitoring state quantity of the hydrogen in real time and calculating mass of the consumed hydrogen by an algorithm, and the hydrogen recycle pipeline is used for separating moisture and air from the hydrogen discharged out of the air outlet of the device, pressurizing the remaining hydrogen and then combining the remaining hydrogen to the main hydrogen supply pipeline. The main hydrogen supply in the device provided by the invention can be used for monitoring the temperature, the pressure and the flowing quantity of the hydrogen in real time and calculating the consumed hydrogen quantity by the algorithm, the pressure and the flowing quantity of the hydrogen at an inlet can be adjusted by the pressure regulation valve group, the temperature of the hydrogen at the inlet can be adjusted by the heating device, so that the optimal working condition of a fuel cell is reached.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to a fuel real-time monitoring and recycling device for fuel cell vehicles. Background technique [0002] Energy shortage and deterioration of the ecological environment are two major problems faced by mankind in the 21st century, and vigorously developing new energy vehicles is a major strategic measure to deal with these two problems. Among many new energy vehicles, fuel cell vehicles have zero emissions (or low emissions), can reduce water pollution caused by oil leakage and air pollution caused by excessive emissions of greenhouse gases, and have high fuel utilization and low operating costs. It is considered to be an important direction for the sustainable development of the automotive industry in the future due to its many advantages such as stability and noiselessness, and it is an ideal solution to solve global energy problems and climate change.

AI Technical Summary

Problems solved by technology

[0007] 1: The fuel supply system is relatively simple, and generally there is no hydrogen recirculation system, which also limits the mileage of fuel cell vehicles. At the same time, hydrogen is a flammable gas, and uncontrolled emissions can easily cause explosion hazards, which need to be disposed of safely

[0008] 2. The existing hydrogen recirculation system does not consider the situation that the outlet hydrogen is doped with air and moisture; in theory, if such recirculated hydrogen is not further processed, it will not be able to reach the inlet hydrogen concentration of the hydrogen fuel cell. Using such recirculated hydrogen , the performance of the battery will decline, unable to meet the work requirements, and even cause danger

[0009] 3. The existing hydrogen supply pipeline cannot monitor the state of hydrogen in real time, adjust the temperature, pressure, and flow of hydrogen at the inlet, and cannot measure the quality of hydrogen consumed at the same time
