Abstract

A fuel cell hydrogen loop direct cold start ice breaking system, comprising: a fuel cell stack, the fuel cell stack includes an air side and a hydrogen side; an air supply subsystem, a hydrogen supply subsystem, the air compressor and an intercooler There is a three-way valve and a fourth switch valve on the pipeline between them, and a check valve is set on the pipeline between the gas-water separator and the hydrogen inlet on the hydrogen side. It is connected with the pipeline between the one-way valve, or between the gas-water separator and the hydrogen circulation pump. The hot air discharged from the air compressor enters the gas-water separator and the hydrogen circulation pump through the three-way and the third switch valve. The ice is broken inside the gas-water separator and the hydrogen circulation pump. The hot air can quickly fill the interior of the hydrogen circulation pump, which can quickly break the ice and melt the frozen parts of the rotor, which takes a short time and has a good ice-breaking effect, so that the hydrogen circulation pump can start up quickly and work normally, ensuring the normal operation of the entire fuel cell system.

Description

Technical field: [0001] The invention relates to a direct cold start ice breaking system of a fuel cell hydrogen circuit. Background technique: [0002] At present, the development of new energy fuel cell vehicles is considered an important link in the transformation of transportation energy and power. In order to ensure the normal operation of fuel cell engines, fuel cell engines generally require auxiliary systems such as hydrogen supply subsystems, air supply subsystems, and circulating water cooling management subsystems. , a large number of studies have shown that high-pressure, high-flow air supply has a significant effect on improving the power output of existing fuel cell engines. [0003] For the air supply subsystem, the air is generally pressurized by an air compressor. For the hydrogen supply subsystem, the hydrogen-containing mixed gas is generally pressurized by a hydrogen circulation pump and circulated back to the fuel cell for recycling. . When working, be...
