Material is input to anode, and hydrogen or other oxidized occurs on the interface of electrode and electrolyte with oxygen also
Former electrochemical reaction, produces electric current, exports electric energy.Compared with thermal power generation mode, sending out of fuel cell
Electric process is without directly burn CO, CO of fuel2、SO2, NOx and unburnt discharge of poisonous waste
Measure extremely low, the after thermoelectricity, water power and nuclear power the 4th kind of generation mode being well recognized as.Therefore, fuel electricity
Pond be integrate the new techniques such as the energy, chemical industry, material and Automated condtrol, have efficient special with cleaning
The new power of color.
Up to the present, fuel cell has occurred in that a variety of technology and structure type, but according to electrolysis
The difference of matter, is generally divided into alkaline fuel cell (Alkaline Fuel Cell, AFC), phosphoric acid fuel cell
(Phosphoric Acid Fuel Cell, PAFC), molten carbonate fuel cell (Molten Carbonate Fuel
Cell, MCFC), solid-oxide fuel cell (Solid Oxide Fuel Cell, SOFC) and PEM
Fuel cell (Proton Electrolyte Membrane Fuel Cell, PEMFC) five big classes.For melted carbonic acid
Salt fuel cell, owing to its advantage has: (1) operating temperature is high, and electrode reaction activation energy is little, no matter hydrogen
Oxidation or the reduction of oxygen, all need not effective catalyst, save the use of noble metal, to a certain extent
Reduce cost；(2) fuel gas that CO content is high can be used, such as coal gas；(3) waste heat of battery discharge
Temperature is up to more than 673K, can be used for bottoming cycle or reclaims use, making total efficiency be up to 80%；(4)
Can not be water-cooled, and cool down with air, be particularly suited for the outlying district of hydropenia, therefore, melted carbon
Hydrochlorate fuel cell is the finest in the application prospect of the aspects such as distributed power station and portable power source.
At present, bipolar plates is one of key equipment of molten carbonate fuel cell, and its effect is to separate oxidation
Gas and fuel gas, play the effect of current collection and conduction, and constitute the passage that gas flows, the most also prevent
Gas is outwardly revealed.Additionally, by the interconnection function of bipolar plates, composition that single battery is together in series combustion
Material battery pile, carries out powerful generating.
In high-power molten carbonate fuel cell pile power generating, battery pile air supply system is typically from battery pile
Two ends air inlet, due to the increase of battery pile height, arises that source of the gas deficiency and middle heat in the middle part of battery pile
Amount evacuates the problems such as difficulty, along with running for a long time, can affect the decline of battery pile output.
Summary of the invention
In order to overcome the problems referred to above, the purpose of this utility model is to provide a kind of for fused carbonate fuel
The bipolar plates of battery pile thermal management, is used for solving the difficult problems such as high-power fused carbonate fuel assembly thermal management.
In order to achieve the above object, the technical solution of the utility model is:
A kind of bipolar plates for molten carbonate fuel cell heap thermal management, the thickness of described bipolar plates 1
It is 100～200mm, the cathode side common line 6 of bipolar plates and the lateral opening hole of anode-side common line 7,
It is respectively welded cathode side air inlet pipe 5 and anode-side air inlet pipe 8.
Described cathode side air inlet pipe 5 and anode-side air inlet pipe 8 are separately installed with gas when being connected with air supply system
One-way control valve.
Described cathode side air inlet pipe 5 and anode-side air inlet pipe 8 is the most separately installed when being connected with air supply system has
Gas flowmeter.
Determine the quantity placing bipolar plates according to battery pile height, lay when 20～40 batteries stack height
One, inside 100 batteries heaps, place 2～3 bipolar plates.
The most relatively, this utility model possesses following advantage:
In the middle part of high-power molten carbonate fuel cell heap, arrange this utility model bipolar plates, this bipolar plates
Anode and negative electrode common-use tunnel lateral opening hole, the air supply system outside battery pile is straight in the middle part of the road direction battery pile of hole
Connect supply, reach the effect that battery pile internal heat adjusts；This utility model can be good at solving melted carbon
In the middle part of hydrochlorate fuel assembly, supply is not enough and middle heat amount dredges a difficult difficult problem so that high-power melted carbonic acid
Salt fuel cell pack output is efficiently modified.
Accompanying drawing explanation
Fig. 1 is this utility model bipolar plates schematic diagram.
Fig. 2 is that high-power molten carbonate fuel cell heap assembles schematic diagram figure.
Wherein 1 is this utility model bipolar plates, and 2 is electrode, and 3 is electrolyte membrance, and 4 is common large area
Light-duty thin bipolar plates, 5 is cathode side air inlet pipe, and 6 is cathode side common line, and 7 is anode-side common line,
