High-power fuel cell and vehicle-mounted hydrogen integration system and method

Abstract

The invention provides a high-power fuel cell and vehicle-mounted hydrogen integration system and method. The high-power fuel cell and vehicle-mounted hydrogen integration system comprises a vehicle-mounted hydrogen supply subsystem, two sets of fuel cells, a heat dissipation assembly, a DC / DC module and an air filter, the vehicle-mounted hydrogen supply subsystem is respectively connected with the two sets of fuel cells and respectively provides hydrogen for the two sets of fuel cells; the heat dissipation assembly is attached to the two sets of fuel cells and is used for dissipating heat of the two sets of fuel cells respectively; the output ends of the two sets of fuel cells respectively supply power to the vehicle through the DC / DC module; the air input ends of the two sets of fuel cells are respectively connected with outside air through an air filter, and the exhaust ends of the two sets of fuel cells are respectively connected to the atmosphere through exhaust pipelines. The system can monitor the running state of the fuel cell and the state of the hydrogen cylinder, and if leakage occurs, a driver can be reminded of the hydrogen leakage state. A driver can be reminded of the collision state of the hydrogen cylinder; the stable operation of the system is ensured, and the safety of the large commercial vehicle is further ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted fuel cells, in particular to a high-power fuel cell and vehicle-mounted hydrogen integrated system and method. Background technique [0002] At present, in order to reduce fuel consumption and environmental pollution caused by fuel, large commercial vehicles use hydrogen fuel as a power source to ensure the driving and operation of large commercial vehicles. [0003] At present, the fuel cell system for large commercial vehicles is developing in the direction of high power, especially for heavy commercial vehicles, which have higher requirements on the power and economy of the vehicle, and the greater the demand for the power of the fuel cell system, especially to meet the response of most working conditions The power of the fuel cell system needs to exceed 160kW and the on-board hydrogen system. The former is responsible for providing electric energy to the vehicle, and the latter is resp...

AI Technical Summary

Problems solved by technology

[0004] The current fuel cell technology is difficult to meet the power needs of large commercial vehicles, and because the fuel cells in the prior art are not monitored in time, in the process of obtaining hydrogen supply, improper monitoring is likely to cause accidents, resulting in unstable driving of large commercial vehicles
