Humidification device of fuel cell

Abstract

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 invention relates to a fuel cell humidifying device. Background technique [0002] A proton exchange membrane fuel cell is a device that generates electricity by electrochemically reacting fuels that generate hydrogen ions with oxidizing gases such as oxygen or air. 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 the continuous operation of the proton exchange membrane fuel cell, the proton exchange membrane in the fuel cell must be kept wet. During the operation of the fuel cell, especially the operation of the fuel cell stack, a large amount of heat will be generated, which will easily vaporize the product water produced in the cathode area, and the rapid flow of the reaction gas will quickly take away the water, ma...
