Abstract
A solid fuel battery tube comprises an inner supporting tube, an outer supporting tube, an inner connection ring, an outer connection ring, an electrode electrolyte tube, conducting wire and a connection body. The adjacent two electrode electrolyte tubes are fixed by the inner and outer connection rings. A fuel gas chamber and an air chamber are respectively formed between the adjacent inner and outer connection rings. The air chamber and fuel gas chamber is sealed up by the inner and outer supporting tubes. The inner supporting tube and outer supporting tube are provided with ventholes on the tube wall and are fixed by the connection body. The inner and outer supporting tubes are connected via the conducting wire. The utility model has simple structure, stable performance and high output power. Coal gas, natural gas, methanol and ethanol can be all taken to be the fuel of the utility model. When hydrogen is taken to be fuel, the power density can reach 200 mW/cm<2>.
Description
The chemical energy that fuel cell directly will be stored in fuel (hydrogen) and the oxidant (air) is converted into electric energy, and its generating efficiency is up to 50-70%, and environmentally safe is a kind of new forms of energy that can substitute fossil fuel of universally acknowledged sustainable development.The generating of fuel cell is to be finished by anode, electrolyte and negative electrode three parts, and ion produces electric current in the electrolyte internal transmission between anode and negative electrode.Fuel cell is pressed the electrolyte classification, makes electrolytical battery with soild oxide and is called solid fuel cell, and the structure of solid fuel cell mainly contains two kinds of forms, and a kind of is flat, and another kind is a tubular type.The pipe of existing tubular type fuel cell is an integral type, and its complex structure repairs very inconvenient.In addition, the intensity of pipe is low, can rupture when being subjected to judder, influences the battery pile normal power generation.
The purpose of this utility model provide a kind of simple in structure, intensity is high, the solid fuel cell pipe of low cost of manufacture, to overcome the defective that prior art exists.
The technical solution of the utility model is: it comprises electrode electrolyte pipe, lead and the connector of interior stay pipe, outer stay pipe, interior connecting ring, outer connecting ring, interval air chamber, facing two effective inside and outside connecting rings of electrode electrolyte mutually fixes, each self-forming fuel gas chamber and air chamber between the adjacent inside and outside connecting ring, air chamber and fuel air chamber are sealed by inside and outside stay pipe, the tube wall of inside and outside stay pipe has air vent hole and is fixed by connector, and lead connects inside and outside stay pipe.
For electric conductivity better, the outside of interior stay pipe and outside the interior side contacts of stay pipe be provided with copper mesh.
Good effect of the present utility model is: simple in structure, stable performance, power output are big, and the power density when being fuel with hydrogen has reached 200mW/cm

Below in conjunction with drawings and Examples the utility model is described in detail.
Accompanying drawing is a structure cutaway view of the present utility model.
With reference to accompanying drawing, the utility model is made up of interior stay pipe 6, outer stay pipe 1, interior connecting ring 7, outer connecting ring 3, electrode electrolyte pipe 5, lead 11 and connector 10, facing two inside and outside connecting rings 7,3 of electrode electrolyte pipe 5 usefulness mutually fixes, each self-forming fuel gas chamber 8 and air chamber 4 between the adjacent inside and outside connecting ring, air chamber 4 and fuel air chamber 8 are by inside and outside stay pipe 6,1 sealing, and the tube wall of inside and outside stay pipe has air vent hole 2 and fixing by connector 10.Wherein the material of stay pipe is stainless steel or the earthenware of handling through metalized surface, better for electric conductivity, be provided with copper mesh 12, copper mesh 12 connection leads 11 in the interior side contacts of the outside of interior stay pipe and outer stay pipe, because copper mesh resistance is little, so conduct electricity very well.About 1 millimeter of the wall thickness of stay pipe, the area of tube wall about 50% is cut to guarantee that air or fuel gas can enter, pass in and out air chamber smoothly.Interior connecting ring and outer connecting ring are shaped as tubular type, it is electronic conductor, the most handy pure copper material, they have the function that supports two stay pipes and connection electrode electrolytic tube, and the electrode electrolyte pipe is cylindrical, preferably has more than two, constitute by anode, electrolyte and negative electrode, anode adopts Ni, electrolyte YSZ (zirconia of stabilized with yttrium oxide), negative electrode LaMnO
3(lanthanum manganate).During making, earlier anode is made pipe, then, YSZ is deposited on the anode tube, again LaMnO
3(lanthanum manganate) is deposited on the YSZ electrolyte.Structure shown in the figure is to be made of 4 electrode electrolyte pipes, and the quantity that constitutes the electrode electrolyte pipe of battery pipe can be chosen arbitrarily, and the quantity total length of battery pipe at most is long.Interior stay pipe and outer stay pipe are respectively two utmost points of battery pipe, and when fuel gas was in the pipe of fuel gas inlet 9 feeding battery pipes, outside the air access tube, interior stay pipe 6 was negative poles, and outer stay pipe 1 is anodal, insulate between them, and is connected with lead 11 respectively.Upper and lower two connectors 10 link together interior stay pipe and outer stay pipe, and this connector is the electronic isolation material.For the ease of assembling and maintenance, inside and outside stay pipe can adopt segmented, and the electrode electrolyte pipe is in the same place by the slight sintering of common technology with inside and outside connecting ring.Inside and outside connecting ring is respectively as the interval body of adjacent fuel air chamber of battery pipe and adjacent air chamber.
During the assembled battery pipe, earlier electrode electrolyte pipe and inside and outside connecting ring are in the same place by the slight sintering of common technology, then, more inside and outside stay pipe are loaded onto and fixedly connected with connector, at last, being connected with lead as positive and negative electrode outward, interior stay pipe.
When the battery plumber did, fuel gas entered inside battery by the fuel gas inlet, and the hole that sees through on the interior stay pipe enters each fuel chambers.Meanwhile also there are spent fuel gas and air to flow out from fuel air chamber and air chamber respectively, remain the freshness of fuel gas and air, the battery pipe can generate electricity at 600-1000 ℃, electric current is drawn by lead through inside and outside stay pipe, every battery pipe can work independently, and also can be assembled into battery pile to them.
