Description

technical field

[0001] The invention relates to a fuel cell humidifier. Background technique

[0002] A fuel cell is a device that converts chemical energy into electrical energy through fuel combustion reactions in the battery. The negative electrode serves as the common interface between the fuel and the electrolyte, and also catalyzes the oxidation reaction of the fuel; while the positive electrode is the common interface between oxygen and the electrolyte. Catalyzes the reduction reaction of oxygen. Fuel cells are divided into phosphoric acid type (PAFC, phosphate fuel cell), molten carbonate type (MCFC, melt carbonate fuel cell), solid oxide type (SOFC, solidoxide fuel cell) and proton exchange membrane type (PEMFC, proton exchange membrane fuel cell). Among them, the proton exchange membrane fuel cell (PEMFC) can work in a low temperature environment. Because it uses a solid electrolyte, it can be applied to industries that require mobile energy, such as the automobi...
