The invention provides a fuel cell humidifying device which includes a gas container, the gas container is provided with a gas inlet and a gas outlet which are communicated with inside of the gas container; wherein, the humidifying device also includes a atomizing nozzle, a water amount adjusting valve and a gas container humidity measurement device; when humidity of gas detected by the gas container humidity measurement device is not in scheduled range, water feeding amount of the atomizing nozzle is adjusted by the water amount adjusting valve until humidity of the gas detected by the gas container humidity measurement device is in the scheduled range. The fuel cell humidifying device is provided with the humidity measurement device, water feeding amount of the atomizing nozzle is adjusted according to detected humidity, so that the fuel cell humidifying device can real-time control humidity.
Description
[0001] This application is a divisional application of an invention patent application named "Fuel Cell Humidifier" with the filing date of November 1, 2006 and the application number of 200610137930.7. technical field [0002] The invention relates to a fuel cell humidifying device. Background technique [0003] 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...
