Description

Gas dew point control device
Technical field
The invention relates to a kind of gas humidity control device, particularly about a kind of gas dew point control device.
Background technology
Fuel battery engines is the core of fuel cell car, also is the focus that various countries try to be the first and capture, and the U.S., Japan, Germany etc. have all classified fuel cell as the national science and technology development priority and built special project, and have obtained many-sided breakthrough.
The factor that influences fuel battery performance is a lot, and wherein Temperature Influence is the most remarkable.Temperature raises, and helps improving electrochemical reaction rates and the transmission speed of proton in proton exchange membrane, obtains bigger electric current, and fuel cell performance is improved.But temperature causes the usefulness of proton exchange to descend the fuel battery performance variation if the too high proton exchange membrane that will make is dewatered on the contrary.Therefore, the temperature of control fuel battery inside electrochemical reaction is crucial.
Humidity also is a key factor that influences fuel battery performance in addition, and the water in the fuel cell comprises gaseous state and two kinds of liquid state, and the source comprises water (at negative electrode) that is generated by electrochemical reaction and the water of being brought into by the reacting gas of humidification.Because the conductivity of the proton exchange membrane of fuel cell can increase with the increase of its water content, if the reacting gas that enters fuel cell is humidification not, then can allow the proton exchange membrane dehydration become dry, cause the internal resistance of fuel cell to rise significantly, reduce the service behaviour of fuel cell, therefore must carry out humidification to reacting gas earlier.
Because fuel cell is subjected to the influence of temperature and humidity very big, therefore the humidifier that reacting gas is used can be set, temperature and humidity when the control reacting gas enters fuel cell.The basic principle of humidifier is that gas and steam are lowered the temperature after being mixed into a wet gas in the high temperature again, when wet gas is cooled to dew point, therefore oversaturated steam can be condensed into water droplet and separate with this wet gas in this wet gas, make at last and reach the purpose of controlling temperature and humidity simultaneously by the state that wet gas reaches capacity.
Patent case about humidifier is existing many, for example: United States Patent (USP) 6,715, No. 743 patent cases, it discloses a kind of gas humidification device, includes a seal groove, a gas access, an evaporator, a heating element, a condenser pipe and a gas vent.A certain amount of water is housed in the sealing groove, and this gas access imports a gas to the water of sealing groove.This evaporator is arranged in the sealing groove, in order to be received from that this gas access imports in sealing groove water and this gas of becoming bubble.This heating element is arranged in this evaporator, produces steam in order to the water in the heating fumigators, makes this steam and this gas be mixed into a wet gas.This wet gas via the condenser pipe on the surface that connects this evaporator outside this gas vent is sent this gas humidification device.Though this patent case is arranged on the below of this evaporator with the gas access, gas can directly be mixed in the way of rising with steam.But also can take away the heat of part during by evaporator simultaneously at gas, and influence the heats of heating element, the poor effect that makes the steam generation.
Similarly be United States Patent (USP) 6,863 in addition, No. 268 patent cases, it discloses a kind of gas moistener, includes prewet device, a gas access, a boiler, one of an airtight container, and mixes an air drain and a gas vent.One gas is imported via this gas access in the water of this device of prewetting and is prewetted, gas after prewetting mixes in this with the steam that this boiler produces and is mixed into a wet gas in the air drain, after this wet gas was cooled off through the formed path, space between this mixing air drain and airtight container inwall, this gas vent was discharged certainly.The mixing air drain of this patent case is a cylinder, and this cylinder covers this prewet device and boiler from the top, imports this in order to supplied gas and steam and mixes in the air drain and mix.But because this cylindrical lower wall is designed to open fully, cover blow vent shape behind this prewet device and boiler just as the ring that is centered around prewet device and boiler periphery, the design of this kind blow vent not only opening is excessive, more because position vicinity prewet device and boiler, gas and steam are just discharged from blow vent earlier before the mixing in entering the mixing air drain, cause mixed effect not good.
Aspect temperature control, the temperature when above-mentioned two patent cases all utilize near the temperature inductor that is arranged on the gas vent to come the sensing wet gas to arrive gas vent is regulated the heating power of heating element or boiler according to this temperature.But because from beginning that at first one section not short distance is arranged between the gas vent to the end of vaporific place, the centre has many factors that influence temperature to exist, temperature when the temperature of wet gas is not generated by initial steam entirely determined, the temperature when therefore this mode is difficult to that accurately the last wet gas of control is exported.
In view of the above, though humidifier on steam produces, gas and steam mix and temperature control on still have the disappearance existence, cause the humidity and the temperature that are difficult to accurately control wet gas.
