Description

technical field [0001] Embodiments of the present invention relate to the field of clean energy technology, and in particular to a hydrogen fuel cell waste heat utilization system. Background technique [0002] A hydrogen fuel cell is an energy conversion device that uses the chemical energy of hydrogen and oxygen in the air to produce electrical energy. Hydrogen fuel cells have the advantages of high conversion efficiency, large capacity, and high specific energy. The application of hydrogen fuel cells on ships as a source of electrical energy has great advantages, such as good mute effect, high work efficiency, and no pollution. However, at present, hydrogen fuel cells will generate a large amount of waste heat during operation. For this part of waste heat, the common practice is to dissipate heat through air cooling equipment. However, when it is applied on a ship, due to the limited space of the ship, it is impossible to install large-scale air cooling equipment, which...
