Humidification tank for fuel cells

Abstract

The invention discloses a humidification tank for fuel cells, which comprises a tank body, wherein the inner top of the tank body is provided with an air outlet, the bottom of the tank body is provided with an air inlet, the tank body is internally provided with a liquid level regulating assembly and a water temperature regulating assembly, both the liquid level regulating assembly and the water temperature regulating assembly are connected with an upper computer, and the liquid level regulating assembly and the water temperature regulating assembly are respectively used for regulating the liquid level and temperature of water in the tank body; the tank body is internally provided with a plurality of isolation plates, the bottom surface of each isolation plate is obliquely arranged, and the isolation plates are used for increasing the travel of air bubbles in the tank body. The humidification tank for fuel cells performs humidification on a reaction gas by applying a bubbling method, and the travel of the humidified air is changed from the original straight line into a curve, thereby increasing the travel, and enhancing the humidification effect. The humidification tank can regulate the liquid level and temperature of water in the tank body through setting the liquid level regulating assembly and the water temperature regulating assembly, thereby realizing the regulation for the humidification effect of the humidification tank.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a humidification tank for fuel cells. Background technique [0002] The working principle of a fuel cell vehicle is that the hydrogen used as fuel in the fuel cell carried by the vehicle undergoes a redox chemical reaction with the oxygen in the atmosphere to generate electricity to drive the motor to work. It has the remarkable characteristics of zero pollution and zero discharge. At the same time, compared with pure electric vehicles, it can overcome the shortcomings of short cruising range and long charging time. Therefore, hydrogen fuel cell vehicles are one of the trends in future vehicle development. [0003] According to different types of electrolytes, fuel cells can be divided into proton exchange membrane fuel cells (PEMFC), alkaline fuel cells (AFC), phosphoric acid fuel cells (PAFC), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC) and direct me...
