Design of the Enthalpy Wheel Humidifier for Fuel Cell Electric Vehicles

The necessity of humidification treatment for reacting gas of the proton exchange film fuel cells is dissertated.In order to resolve the problem that it is difficult for typical methods to adjust humidification degree, advantages and the working principle of the enthalpy wheel humidifier whose humidification degree is adjustable are introduced.Design of the enthalpy wheel humidifier is introduced from design consideration,determination of enthalpy wheel dimensions,selection of the electric motor and sealing.Preliminary experimental study on the designed enthalpy wheel humidifier was carried out and the test results are given.
