The present invention provides a fuel cell humidifier, including a gas container. The gas container is provided with a gas inlet and a gas outlet communicated with the interior of the gas container; wherein, the humidifier also includes an atomizer, a water control valve and a humidity measuring device of gas container; when the humidity measuring device of gas container detects that the gas humidity is not within the preset range, the inflow in the atomizer will be adjusted through the water control valve until the humidity measuring device of gas container detects that the gas humidity is within the preset range. The fuel cell humidifier provided by the present invention introduces a humidity measuring device so as to carry out the real-time control on the gas humidity according to the detected inflow of the atomizer through humidity adjustment.
Description
technical field [0001] The present invention relates to a fuel cell humidification device. Background technique [0002] A proton exchange membrane fuel cell is a device that generates electricity by electrochemically reacting a fuel that produces hydrogen ions with an oxidizing gas such as oxygen or air. When the proton exchange membrane fuel cell works, the protons in the cell are all conducted through the proton exchange membrane. Specifically, proton transfer is carried out in a manner of hydrated protons, thereby forming an electric current. Therefore, in order to ensure that the proton exchange membrane fuel cell can work continuously, it is necessary to keep the proton exchange membrane in the fuel cell wet. During the operation of the fuel cell, especially the operation of the fuel cell stack, a large amount of heat will be generated, and it is easy to vaporize the product water produced in the cathode area, and the rapid flow of the reaction gas will quickly take ...
