Description
Technical field
The utility model belongs to the Solid Oxide Fuel Cell technical field, relates in particular to the direct flame solid oxide fuel battery device of a kind of tubular type.
Background technology
Solid Oxide Fuel Cell (SOFC) work has many-sided advantages such as efficient height, power density is big, simple in structure, fuel tolerance is wide, in large, medium and small type power station, there is wide application prospect in fields such as movable type, compact power and military affairs, Aero-Space.
Traditional SOFC is separated fuel and oxidant gas by two air chambers usually, can between anode and cathode, keep higher chemical potential gradient, to realize higher generating efficiency and fuel availability, but the quality of two chambers SOFC sealing property directly affects battery performance, and the coupling of the encapsulant and the battery material coefficient of expansion is one of two business-like difficult points of chamber SOFC all the time when variations in temperature especially.Single chamber SOFC is the SOFC battery configuration of a class novelty,, utilizes its anode, negative electrode that the difference of fuel, oxidant gas catalytic activity is produced electrical potential difference and carries out work simultaneously as the atmosphere of galvanic anode and negative electrode with the fuel-oxidant mixtures body.Compare two chamber SOFC, single chamber SOFC structure is relative with manufacturing process simple, reduced battery to system sealing requirement and device complexity, but the battery fuel utilance differs greatly with two chamber SOFC, simultaneously the selection of electrode materials catalytic activity is had relatively high expectations, increased manufacturing cost.In addition, fuel directly mixes with oxygen in the battery, has the danger of blast, must consider fuel blast limit problem, and the adjustable range of reaction atmosphere is restricted.
The researchers such as Horiuchi of Japan Sinkoudenki K. K (Shinko Electric Industries) have proposed directly flame SOFC battery configuration of structure more simple " no chamber " first, utilize the gas component such as the H that produce under the rich burning state
2And CO is as the SOFC anode reaction gas.Flame is used for consumable anode side oxygen components to guarantee the chemical potential gradient between negative electrode, the anode under " no chamber " condition, heats SOFC simultaneously to required working temperature.Directly the main advantage of flame SOFC is: (1) is fuel tolerance widely: can use multiclass fuel gas, liquid, solid to act as a fuel, in fact these fuel rich combustion flame compositions all mainly comprise hydrogen, water, CO, CO
2And free radical compositions such as CH, OH, the hydrocarbon fuel after reforming is similar with using; (2) apparatus structure is simple, only the anode negative electrode need be placed among flame and the air, need not sealing; (3), be expected to obtain higher cogeneration of heat and power overall efficiency although generating efficiency is relatively low; (4) start fast, flame directly can be used as SOFC and starts thermal source, need not the additional configuration thermal management; (5) galvanic anode, negative electrode office flame, oxidant atmosphere need not design and have well optionally eelctro-catalyst, can directly use the most ripe at present Ni-YSZ|YSZ|LSM-YSZ membrane electrode system, are expected effectively to reduce manufacturing cost; (6) galvanic anode is a partial oxidation atmosphere, and electrode surface carbon distribution problem still is that the dynamics aspect is considered all will greatly alleviate from thermodynamics.These advantages make direct flame SOFC become the new configuration of fuel cell that a class has the important application prospect, be expected to especially be applied to fields such as cogeneration of heat and power, military project, Aero-Space, significant to the research of direct flame SOFC for the progress and the national energy security of China's energy technology.
Directly flame SOFC is still a brand-new research topic at present, and the research work about direct flame SOFC both at home and abroad all is in the starting stage, and relevant report is less.Battery performance when people such as Horicuchi utilize common pipe burner that SOFC is placed butane, kerosene, solid paraffin and timber fuel-rich flame respectively, power of battery density reach 75,65,62 and 5mW/cm respectively
2, and in butane flame, obtained the peak power density of 318mW by the mode of 4 batteries polyphones.A Kronemayer mistake of Duisburg, Germany-Ai Sen university! Do not find Reference source.And the researchers such as Vogler, Bessler of Ruprecht-Karls-Universitat Heidelberg and Japanese Sinkoudenki K. K cooperate to utilize equally the McKenna burner to study gas with various fuel (methane, propane and butane) and different flame operating condition parameter to direct flame SOFC Effect on Performance, and the battery peak power density reaches 200mW/cm
2Domestic teacher Shao Zongping of Institutes Of Technology Of Nanjing utilizes alcolhol burner that the performance of direct ethanol flames SOFC is studied, and utilizes the ethanol flames internal flame to cooperate with the galvanic anode that has increased Catalytic Layer, makes power of battery density peaks reach 200mW/cm
2
The space structure distribution character that studies show that flame that carries out at present direct flame fuel battery both at home and abroad causes uneven battery operated temperature easily, gas and primitive component, make to have thermal stress in the battery operated process, cause battery performance to quicken decay easily.And the research and the application of the direct flame solid oxide fuel battery of still unmatchful tubular type at present.
