Abstract

The invention discloses a hydrogen supply system for rapidly judging a hydrogen leakage part. The hydrogen supply system for rapidly judging the hydrogen leakage part mainly comprises a hydrogen storage tank, an overflowing valve, a pressure reducing valve, an electromagnetic valve, a fuel cell stack, a hydrogen circulating pump, a moisture separator, a drainage valve, a high pressure cylinder valve, a hydrogen inlet, a hydrogen outlet, pressure sensors, a low pressure stop valve, a one-way valve, an exhaust valve, a high pressure stop valve, a blowoff valve, a vehicle-mounted computer, a hydrogen supply system state display and the like. According to the hydrogen supply system for rapidly judging the hydrogen leakage part, a self-inspection state when the system is started can be comparedwith a signal and a safety value of the vehicle-mounted computer fed back by the pressure sensors during normal work to judge whether hydrogen leaks or not, and assemblies with the problem can be rapidly positioned according to the sensors with abnormal pressure. The hydrogen supply system for rapidly judging the hydrogen leakage part is applied to hydrogen fuel cell passenger vehicles and hydrogen fuel cell commercial vehicles, a working state of the hydrogen supply system can be monitored in real time and the problem assemblies can be rapidly positioned, and the safety of the vehicles in the use process is improved.

Description

technical field [0001] The invention belongs to the field of fuel cell power systems, and in particular relates to a hydrogen supply system for quickly judging hydrogen leakage locations. Background technique [0002] A fuel cell is a power generation device that directly converts the chemical energy in fuel into electrical energy through an electrochemical reaction. Among them, the proton exchange membrane fuel cell has low operating temperature and fast start-up speed, and is the first choice for vehicle fuel cells. The working mode of the fuel cell is similar to that of the internal combustion engine, and its fuel is carried outside the battery. The hydrogen used in the fuel cell can be filled as fast as traditional gasoline, and it only takes a few minutes. Therefore, the fuel cell has a greater capacity than a pure electric vehicle. Application advantages. Fuel cell vehicles have certain similarities with traditional vehicles in terms of hydrogen refueling and driving...
