Description
Technical field
The present invention relates to a kind of water tank, specifically a kind of multipurpose water tank for the fuel cell cold start-up.
Background technology
The advantages such as that fuel cell has is pollution-free, high energy ratio, high efficiency, automobile industry is all being actively pushed forward the commercialization process of fuel cell car at present, but also exist various challenges, as: the infrastructure construction problems such as the accumulating of reliability, durability, cost and hydrogen fuel and filling etc.One of except these problems, fuel battery engines cold start-up ability also is restriction FCV(fuel cell car) significant challenge of commercial applications.For finishing the fuel cell pile Cold Start, special temperature is lower than-20 ℃ Cold Start, generally all needs to use the mode of assistant starting to finish.This process mainly realizes that by following three kinds of modes fuel cell heats up:
1, hydrogen or methyl alcohol are directly burnt or be catalytically converted into heat, and conduction is to the circulatory system or directly finish this process in pile inside;
2, have externally fed mode or fuel cell self generating to supply with heating wire, heating circulation system or air system reach the whole purpose that heats up;
3, improve the compression ratio of air feeding unit such as air compressor machine, realize the intake air temperature increase, thereby finish auxiliary heating pile process.
The problem that exists is that using single temperature-rising method in same system is the toggle speed that is unfavorable for system; In addition, all there is the problem that does not take full advantage of engine operation waste heat in three kinds of temperature-rising methods more than enumerating; Have, often face a problem when using catalysis method to process fuel cell hydrogen tail row, the air of namely sneaking into can't cool off the used heat that produces in the catalytic process, and this processes for follow-up tail exhaust body is dangerous and disadvantageous.Therefore, how to realize under the fuel cell freezing point starting fast, and to alleviate as much as possible or eliminates the low-temperature circulating startup be a urgent problem to the damage of fuel cell.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of multipurpose water tank for the fuel cell cold start-up.Water tank is mainly used in storing circulation fluid in fuel cell system, to system carry out that solution replenishes, bubble discharging etc.The present invention fully utilizes above three kinds of temperature-rising methods by the redesign to original water tank, increases its function, has solved fuel cell in the not enough problem of the external heating power of Cold Start.Simultaneously, can also be as the hydrogen tail discharge gas treatment at this water tank of fuel cell normal operating phase, making wherein, density of hydrogen is lower than the explosion limit value.
The technological means that the present invention adopts is as follows:
A kind of multipurpose water tank for the fuel cell cold start-up comprises that end socket protecgulum, end socket, water tank main body and tail row collect end socket, and it is characterized in that: described end socket protecgulum is provided with air inlet canister aperture and hydrogen gas pipe; Described end socket is provided with at least two hydrogen gas holes, and a side of described end socket is provided with the hydrogen snorkel that is fixedly connected with described hydrogen gas hole, and the opposite side of described end socket is provided with the air intake duct that is complementary with described air inlet canister aperture; Be provided with the catalysing tube corresponding with described hydrogen snorkel in the described water tank main body, the tube wall inboard of described catalysing tube is provided with can be with the catalyst of hydrogen and oxygen catalytic reaction Cheng Shui, also be provided with at least one heating rod in the described water tank main body, be respectively equipped with cooling fluid entrance and cooling liquid outlet on the described water tank main body; Described end socket protecgulum, described end socket, described water tank main body and described exhaust collection end socket are fixedly connected sequentially.
The caliber of described hydrogen snorkel is less than the caliber of described catalysing tube.
Catalyst in the described catalysing tube is at least platinum black, palladium, rhodium and alloy thereof, Pt/c, Cu

4In a kind of.
The mouth of pipe of described hydrogen snorkel is the sharp-mouth type mouth of pipe.
Water tank main body of the present invention is used for storing cooling fluid, and participates in the circulation of cooling system.Catalysing tube in being arranged on the interior hydrogen snorkel of end socket and being arranged on the water tank main body is corresponding one by one, the caliber of hydrogen snorkel is less than the caliber of catalysing tube, the air velocity of hydrogen flow rate outside the hydrogen snorkel in the hydrogen snorkel, the port of export at the hydrogen snorkel, because the speed difference of hydrogen and air and is finished H so that large quantity of air together is involved in the catalysing tube in catalysing tube
2+ O
2→ H
2The catalytic reaction of O produces simultaneously water and emits heat.
Air intake duct of the present invention is connected with the air tail row pipeline of fuel cell system; The hydrogen gas pipe links to each other with the hydrogen tail discharge mouth of fuel cell system; In the circulatory system that cooling fluid entrance on the water tank main body and cooling liquid outlet are connected on fuel cell system; Heating rod can power taking and control from fuel cell system.
Compare than prior art, the function that the present invention has not only kept original water tank namely stores cooling fluid, liquid level shows, has also increased the auxiliary function that heats up and the function of diluting tail row density of hydrogen in fuel cell cold-starting process.Take full advantage of the heat that system produces, from reclaiming fuel cell system high temperature air, catalytic way recovery fuel cell system hydrogen tail discharge energy and three directions of electric heating, accelerate the temperature rise speed of systemic circulation liquid.Air behind the process fuel cell reaction and hydrogen are mixed into and carry out catalytic reaction in the water tank main body, because the flow of air much larger than the flow of hydrogen, air and hydrogen mixing, can effectively reduce density of hydrogen after the reaction; In addition, reacted content of oxygen in air is lower, can make with the mixed concentration of hydrogen by control to be lower than again the hydrogen explosion limting concentration; And the water tank main body is owing to adopt tube shell type structure, the temperature of the heating rod in the water tank main body can be effectively controlled, thereby the temperature in the catalysing tube also can be effectively controlled, and also can not cause because gathering strength the ignite situation of hydrogen cause danger of high temperature to occur even work at normal temperatures.
The present invention is highly integrated, and is simple in structure, high without rotatable components and reliability, and the present invention can extensively promote in power station and the field such as vehicle-mounted for the foregoing reasons, and possesses preferably application prospect.
