Description
Technical Field
The invention relates to the field of fuel cells, in particular to a high-power fuel cell aeration humidifying device.
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.
In the current practical application, the humidifiers for humidifying the reaction gas of the fuel cell are mainly the following, namely the membrane humidifier: humidifying the gas by diffusion of moisture in the membrane; enthalpy wheel humidifier: humidifying through enthalpy wheel dry-wet conversion; spraying and humidifying: heating and spraying reaction gas; bubbling and humidifying: the reaction gas is humidified by a vessel containing heated liquid water and glass beads at the bottom.
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 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 that the equipment is simple and convenient, high humidity can be obtained at a small flow, the temperature and the humidity are difficult to accurately control, the humidifying cannot timely and synchronously respond to the battery when the battery is quickly started or the load is suddenly and greatly changed, and in addition, excessive liquid water is brought out after the gas is bubbled through the water container at a large flow, so that the liquid water at the outlet of the water lifting container is accumulated.
