Problems solved by technology

The patent retrieval of the prior art found that the authorized announcement numbers are CN102013502A, CN202019023U, and CN202019024U patents all use enthalpy wheels made of ceramic materials, but the enthalpy wheels made of ceramic materials have the following problems: (1) The density of ceramics is large, which increases the quality of the system And the power consumption of the rotating motor, especially when used in automobiles, is sensitive to weight and power consumption (efficiency); (2) The problem of ceramic wear is serious, and the wear between the ceramic enthalpy wheel and the housing will cause the enthalpy wheel and The increase of the gap between the shells will cause the exhaust gas of the fuel cell to be mixed into the fresh air, which will reduce the oxygen concentration in the intake air after humidification; (3) The friction resistance of ceramics as a humidification enthalpy wheel is relatively large, power consumption and noise Larger, affecting the life of the humidifier
Due to these problems, ceramic enthalpy wheel humidifiers cannot well meet the high efficiency and long-term operation requirements of fuel cell systems

Description

technical field [0001] The invention relates to a manufacturing method of a humidifier used in a fuel cell, in particular to a manufacturing method of an enthalpy wheel humidifier used in a proton exchange membrane fuel cell. Background technique [0002] A fuel cell is a clean, efficient, and long-life power generating device. Compared with conventional power generation technologies, fuel cells have great advantages in terms of efficiency, safety, reliability, flexibility, cleanliness, and operational performance, and their application prospects are very broad. As a kind of fuel cell, proton exchange membrane fuel cell also has the advantages of low operating temperature, high specific energy, long service life, fast response speed, and no electrolyte leakage. It has a good application prospect. During the operation of the proton exchange membrane fuel cell, the humidity control of the cathode intake air (air) is one of the most important links. On the one hand, if the a...
