Abstract

The invention provides a fuel cell humidifier device, a fuel cell system and a humidifying treatment method thereof. The humidifier device comprises a shell, middle-through fiber membrane tubes, a diaphragm and an end cap, a first gas inlet and a first gas outlet for wet gas are formed in the same sides of the two ends of the shell, and the middle-through fiber membrane tubes have different diameters; and the middle-through fiber membrane tubes are located in the shell, the shell is divided into an upper cavity and a lower cavity by the diaphragm, the middle-through fiber membrane tubes suitable for circulation of the dry gas are arranged in the upper cavity, and the middle-through fiber membrane tubes suitable for circulation of the wet gas are arranged in the lower cavity. A plurality of micropores are evenly distributed in the middle of the diaphragm, the wet gas is suitable for entering the upper cavity from the lower cavity through the micropores, and the end cap is provided with a second gas inlet and a second gas outlet for dry gas. According to the novel structure designed in the invention, and the problem that an existing physical humidifier is prone to water accumulation, and operation of a fuel cell is affected is solved.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a fuel cell humidifier device, a fuel cell system and a humidification treatment method thereof. Background technique [0002] During the test process of the fuel cell system, the adjustment of the air humidity is also very important, and one of the most important components affecting the air humidity is the humidifier. Through the humidifier, the humidity of the fuel cell stack air can be adjusted, thus helping to prolong the service life of the fuel cell stack. [0003] However, at present, the humidifier in the test bench is a physical humidifier, and the physical humidifier is prone to water accumulation, which will easily make the relative humidity of the air entering the pile higher than the corresponding value, which breaks the When the water balance inside the battery is serious, the inside of the stack will be flooded, which will reduce the operating performance o...
