Description

technical field [0001] The invention relates to the technical field of a hybrid power system of a fuel cell vehicle, in particular to a temperature control power generation device based on a fuel cell and a lithium battery. Background technique [0002] At present, hydrogen energy fuel cells have the advantages of high power generation efficiency, no pollution, no noise, fast cold start, and high specific power. Hydrogen energy fuel vehicles use hydrogen as the main energy source for mobile vehicles. General internal combustion engines are usually injected with diesel or gasoline. , Hydrogen cars use gaseous hydrogen instead. Fuel cells and electric motors will replace ordinary engines, that is, hydrogen is input into the fuel cells, and finally discharged as pure water mist, which effectively reduces the air pollution caused by other fuel-fueled vehicles. Using a fuel cell system as a power source is a hallmark feature of a fuel cell vehicle power system. However, due to t...
