Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heat management system for a hydrogen fuel cell vehicle. Background technique [0002] A hydrogen fuel cell is a power generation device that converts chemical energy into electrical energy by electrochemically reacting hydrogen with oxygen in the air. Its power generation efficiency is generally around 50%. It is beneficial to the electrochemical reaction, but it will also have an adverse effect on the life of the proton exchange membrane. If the control is unreasonable, it will cause water flooding or the proton membrane to dry up, which will adversely affect the performance of the hydrogen fuel cell. Therefore, it is very necessary for electric vehicles to thermally manage the hydrogen fuel cells inside them. [0003] At present, the thermal management system of hydrogen fuel cell electric vehicles uses a deionizer in the coolant circulation loop to remove condu...
