Abstract

The invention relates to a fuel cell system and a fuel cell vehicle. The fuel cell system comprises a first heat exchanger, a first air blower, a first valve, a second heat exchanger and a third heatexchanger, wherein low-temperature hydrogen exchanges heat with air through the first heat exchanger, low-temperature air enters a space to be subjected to temperature adjustment to achieve the cooling of the space to be subjected to temperature adjustment, a high-temperature cooling liquid exchanges heat with air through the second heat exchanger, high-temperature air enters the space to be subjected to temperature adjustment to achieve the temperature rise of the space to be subjected to temperature adjustment, and the third heat exchanger enables low-temperature hydrogen to exchange heat with high-temperature cooling liquid, so that temperature rise of hydrogen and cooling of the cooling liquid are achieved so as to guarantee that the fuel cell stack works in the optimal state. According to the fuel cell system, through the first heat exchanger, the second heat exchanger and the third heat exchanger, heating of hydrogen, cooling of cooling liquid and adjustment of the temperature ofthe space to be subjected to temperature adjustment are achieved, so that comprehensive utilization of internal energy of the fuel cell vehicle is achieved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a fuel cell system and a fuel cell vehicle. Background technique [0002] Energy depletion and environmental pollution caused by fossil energy consumption are becoming increasingly serious, and large-scale development and utilization of renewable energy is imperative. Hydrogen is an effective energy storage method: during the peak period of renewable energy power generation, electrical energy is converted into chemical energy and stored in hydrogen, and the energy carried by hydrogen is converted into electrical energy through fuel cells for use during the peak period of electricity consumption. Hydrogen fuel cell vehicles have the characteristics of zero emission, no pollution, and high efficiency, and are a very promising new energy vehicle. [0003] When a hydrogen fuel cell engine is matched with a liquid hydrogen or high-pressure hydrogen system, the liquid hy...
