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
The fuel cell is a clean, efficient and long-life power generation device. Compared with the conventional power generation technology, the fuel cell has great advantages in the aspects of efficiency, safety, reliability, flexibility, cleanliness, operation performance and the like, and has very broad application prospect. As one of the fuel cells, the proton exchange membrane fuel cell 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 prospect in the aspects of national defense, energy, traffic, environmental protection, communication and the like. Humidity control of the cathode inlet (air) is one of the most important links in the operation of proton exchange membrane fuel cells. On the one hand, if the air humidity is too low, the proton exchange membrane can be dehydrated or dried up, the proton conduction capacity of the membrane is closely related to the water content (wetting state) of the membrane, when the membrane is in a good wetting state, the membrane has high proton conduction capacity, the drying up of the membrane can lead to the reduction of the proton conduction capacity, the increase of the membrane resistance, the increase of ohmic loss and the reduction of the battery performance; meanwhile, the mechanical strength is reduced, and the membrane is broken when serious, so that the hydrogen and the oxygen are mixed and explosion occurs. On the other hand, if the air humidity is too high, excessive water accumulation in the battery can be caused, so that the catalyst in the electrode is pickled by water, the reactivity is reduced, and a gas-liquid two-phase flow can be formed in the flow channel and the diffusion layer, so that partial blockage is caused, the gas mass transfer process is blocked, the supply of the reaction gas is insufficient, the output performance of the fuel cell is reduced, and the operation of the battery is influenced. Therefore, humidity control of the fuel cell reactant gases, particularly air humidity control, is critical in proton exchange membrane fuel cell operation, and is one of the important control links.
In current practice, humidifiers for humidifying fuel cell intake air are mainly: a membrane humidifier for humidifying the gas by diffusion of moisture in the membrane; an enthalpy wheel humidifier for humidifying through an enthalpy wheel; heating and humidifying, wherein the reaction gas passes through a bubbler, and humidifying control, also called bubbling and humidifying, is performed by controlling the water temperature of the bubbler.
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 water permeable but impermeable, and has one side in contact with the wet plate and the other side being a diffusion layer made of an elastic, electrically conductive, breathable material. However, membrane humidifiers have sealing and pressure bearing problems because the polymer membrane swells in water, and repeated swelling-shrinking of the membrane between dry-wet conditions can result in detachment from the sealing surface, thus leakage occurs; in addition, the polymer film is an organic material, is easy to deform, has poor pressure resistance, and can be broken under the action of air pressure in the use process.
The enthalpy wheel humidifies and absorbs water from one side through the water absorbing material on the rotating wheel to heat, and the other side releases moisture and releases heat to achieve the effect of humidifying the reaction gas; the defects are that a motor is required to drive, electric energy is consumed, sealing is not easy to realize, and the like.
The heating and humidifying step is to humidify the reaction gas by a water temperature control bubbler, which is also called bubbling humidification; the bubbler is a container filled with liquid water and glass beads at the bottom, the air inlet is directly led to the bottom of the container through a straight pipe, contacts with small balls capable of increasing the evaporation area, and finally discharges nearly saturated gas through another pipeline on the liquid surface. The humidifying method has the advantages that the equipment structure is simple, the process is simple and convenient, and high humidity can be obtained at a low flow rate; the disadvantage is that the temperature and humidity are difficult to control accurately, when the battery is started up quickly and the active load changes suddenly and greatly, the humidification cannot respond synchronously with the battery in time, in addition, at a large flow rate, the 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 accumulated.
