Abstract

The invention provides a fuel cell humidification system, which includes: a water tank, the lower part of the partition of the water tank is a water storage space, and a dual-fluid injector is arranged above the partition of the water tank, and the dual-fluid injector has a water inlet and communicates with the water storage space ;A compressed air inlet is provided on the upper side of the water tank, and the compressed air enters the upper space of the water tank partition from the compressed air inlet, and the dual-fluid injector has an air inlet; water and compressed air are mixed in the dual-fluid injector and discharged to the upper part In the space, the water tank is also provided with a compressed air outlet; and the dual-fluid injector can adjust the flow rate of water entering the dual-fluid injector according to the air humidity of the compressed air outlet. The invention can effectively humidify the compressed air, and can effectively adjust the size of the water flow according to the humidity of the air, and timely adjust the humidity of the reaction gas entering the fuel cell. The spray atomization quality is high and the spray humidity can be adjusted Adjustment, processing technology is simple.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell humidification system. Background technique [0002] A proton exchange membrane battery is a power generation system that converts the chemical energy of fuel into electrical energy by chemically reacting with oxygen or other oxidants. When the proton exchange membrane fuel cell is working, the protons in the battery are conducted through the proton exchange membrane. Specifically, proton transfer is carried out in the form of a hydrated proton, thereby forming an electric current. Therefore, in order to ensure that the proton exchange membrane fuel cell can work normally, it is necessary to keep the proton exchange membrane of the fuel cell wet. At the same time, during the working process of the fuel cell, a large amount of heat will be generated, which will easily vaporize the water generated in the cathode area, and the rapid flow of the reaction gas will tak...
