Problems solved by technology

Proton exchange membrane fuel cells have high requirements for the ion concentration of the cooling liquid. If the conductivity is too high, the ion reaction rate inside the fuel cell will be reduced. If the concentration of hydrogen and oxygen is too low, the life of the stack will be affected. If the gas supply pressure is too low, the fuel will be affected. The battery reacts, and the gas supply pressure is too high to damage the stack body

The galvanic pile is connected with a cooling liquid circulation system, an air supply circulation system and a hydrogen supply circulation system, the air supply circulation system provides humidified air for the galvanic pile, and the hydrogen supply circulation system provides hydrogen for the galvanic pile; and the cooling liquid circulation system comprises a liquid inlet pipeline and a liquid outlet pipeline which are connected with the galvanic pile, the liquid inlet pipeline is provided with a deionizer, and the liquid outlet pipeline is provided with a conductivity meter and a filter.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a proton exchange membrane fuel cell engine. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As a new type of energy storage device, a fuel cell is an energy conversion device that converts chemical energy into electrical energy by inputting hydrogen and oxygen to undergo a chemical reaction inside the stack. Because of its non-polluting performance, it has been vigorously promoted. [0004] For proton exchange membrane fuel cells, the input pressure, flow rate, concentration of hydrogen and oxygen, and the working temperature of the stack will affect the service life and working efficiency of the stack. At the same time, sufficient hydrogen and oxygen should be given to the fuel cell. Proton exchange membrane fuel cells have high requ...
