Description
Technical Field
The invention belongs to the field of fuel cells, and particularly relates to a fuel cell atomization humidification system and a humidification method thereof.
Background
Fuel cells are clean, efficient, and long-lived power generation devices. Compared with the conventional power generation technology, the fuel cell has great advantages in the aspects of efficiency, safety, reliability, flexibility, cleanness, operating performance and the like, and has a very wide application prospect. As one of the fuel cells, the proton exchange membrane fuel cell also has the advantages of low operation temperature, high specific energy, long service life, high response speed, no electrolyte leakage and the like, and has good application prospects in the aspects of national defense, energy, traffic, environmental protection, communication and the like. Humidity control of cathode inlet air (air) is one of the most important links in the operation of pem fuel cells. On one hand, if the air humidity is too low, dehydration or withering of the proton exchange membrane can be caused, the proton conductivity of the membrane is closely related to the water content (wet state) of the membrane, when the membrane is in a good wet state, the membrane has high proton conductivity, and the withering of the membrane can cause reduction of the proton conductivity, increase of membrane resistance, increase of ohmic loss and reduction of battery performance; and meanwhile, the mechanical strength is reduced, and the film is cracked when the mechanical strength is serious, so that hydrogen and oxygen are mixed and explode. On the other hand, if the air humidity is too high, the water accumulation in the battery is too much, so that the catalyst in the electrode is pickled by water, the reaction activity is reduced, gas-liquid two-phase flow is formed in the flow channel and the diffusion layer, the local blockage is caused, the gas mass transfer process is blocked, the reaction gas is not supplied enough, the output performance of the fuel battery is reduced, and the battery operation is influenced. Therefore, humidity control of the reaction gas of the fuel cell, especially air humidity control, is important in the operation of the proton exchange membrane fuel cell and is one of the important control links.
In the current practical application, the humidifiers for humidifying the intake air of the fuel cell mainly include: a membrane humidifier humidifying the gas by diffusion of moisture in the membrane; an enthalpy wheel humidifier for humidifying through an enthalpy wheel; heating and humidifying, wherein reaction gas passes through the bubbler, and the temperature of the water in the bubbler is controlled to perform humidification control, which is also called bubbling humidification.
The membrane humidifier has the characteristics of compact structure, low pressure drop and the like, and the typical structure of the membrane humidifier comprises a wet plate, a polymer membrane, a diffusion layer and a dry plate, wherein a flow channel on the dry plate is used for circulating and humidifying dry gas, and a humidifying channel is arranged on the wet plate. The membrane material is permeable to water but not to air, and has one side in contact with the wet plate and the other side provided with a diffusion layer made of an elastic, electrically conductive, air permeable material. However, the membrane humidifier has the problems of sealing and pressure bearing, because the polymer membrane swells when meeting water, and the membrane repeatedly swells and shrinks between a dry state and a wet state, so that the membrane can be separated from a sealing surface, and leakage can occur; in addition, the polymer film is an organic material, is easily deformed, has poor pressure resistance, and may be broken by air pressure during use.
The enthalpy wheel is humidified, water is absorbed from one side to increase the temperature through a water absorbing material on the rotating wheel, and the other side releases moisture and releases heat to achieve the effect of humidifying reaction gas; the defects of motor drive, electric energy consumption, difficult sealing and the like are needed.
The heating and humidifying means that the reaction gas is humidified by a water temperature control bubbler, which is also called bubbling and humidifying; the bubbler is a container filled with liquid water and glass beads at the bottom, the inlet gas is directly communicated to the bottom of the container through a straight pipe, and is contacted with a small ball capable of increasing the evaporation area, and finally, the nearly saturated gas is discharged through another pipeline on the liquid surface. The humidifying method has the advantages of simple equipment structure, simple and convenient process, and capability of obtaining high humidity under the condition of small flow; the defects are that the temperature and the humidity are difficult to accurately control, when the battery is quickly started and the active load is suddenly changed to a large extent, humidification cannot synchronously respond with the active load in time, and in addition, when the flow is large, gas bubbles through the water container and brings out excessive liquid water, so that the liquid water at the outlet of the water container is gathered.
