Abstract
The invention discloses a sealing material for a solid oxide fuel battery stack. The sealing material is characterized by comprising the following components in percentage by weight: 10-30 percent of vermiculite powder, 10-25 percent of white mica powder, 5-15 percent of aluminum oxide, 30-40 percent of calcium silicate, 3-7 percent of an adhesive and 3-10 percent of a curing agent. The sealing material has the beneficial effects that sealed connection can be realized at room temperature, and the implementation is convenient; the sealing material is not wasted, so that cost can be reduced; leakage can be detected at room temperature, so that the success rate of a pile can be greatly improved; raw materials are mostly natural minerals with low price, so that the cost can be greatly reduced; on the other hand, the sealing effect is good, the material is pressurized in the curing process to enable the battery and a current collection material to be well contacted, and the sealing performance can be further improved, and resistor contact can be reduced due to high expansion of mica and vermiculite in the heating process.
Description
Technical field
The present invention relates to a kind of encapsulant, particularly relate to a kind of solid-oxide fuel cell stack encapsulant.
Background technology
Solid Oxide Fuel Cell is a kind of efficient, clean, quiet and reliable electrochemical generating unit, is suitable as dispersion, portable power source or big-and-middle-sized power station, all has broad application prospects at electric power, transport and military aspect.Consider for future source of energy strategy, environmental protection, the research of generation technology is devoted in countries in the world always, but sealing problem is one of technical difficult points of restriction Solid Oxide Fuel Cell development always.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of solid-oxide fuel cell stack encapsulant.
The technical solution used in the present invention is:
A kind of solid-oxide fuel cell stack encapsulant, comprises the component of following percentage by weight: vermiculite power 10-30%, white mica powder 10-25%, aluminium oxide 5-15%, calcium silicates 30-40%, binding agent 3-7%, curing agent 3-10%.
Described binding agent is selected from silester or aluminium dihydrogen phosphate.
Described curing agent is selected from magnesium oxide or calcium oxide.
Can also add percentage by weight is transition metal oxide within 0.5%.
Described transition metal oxide is iron oxide, cupric oxide, cobalt oxide or nickel oxide one wherein.
The invention has the beneficial effects as follows: room temperature can realize sealing-in, it is convenient to implement, and does not waste encapsulant, cost-saving, room temperature can be hunted leak, and greatly improves the success rate of pile, the raw material adopted are mostly natural mineral matters, and low price can greatly reduce costs; On the other hand, good sealing effect, in this material cured process, pressurization makes battery contact with current-collecting member well, because the height expansion of mica and vermiculite can improve sealing further and reduce contact resistance in temperature-rise period.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment, only for explaining the present invention, does not form the restriction to protection scope of the present invention.

The invention has the beneficial effects as follows: room temperature can realize sealing-in, it is convenient to implement, and does not waste encapsulant, cost-saving, room temperature can be hunted leak, and greatly improves the success rate of pile, the raw material adopted are mostly natural mineral matters, and low price can greatly reduce costs; On the other hand, good sealing effect, in this material cured process, pressurization makes battery contact with current-collecting member well, because the height expansion of mica and vermiculite can improve sealing further and reduce contact resistance in temperature-rise period.
By vermiculite power, white mica powder, aluminium oxide, calcium silicates, silester and magnesium oxide, adopt and be directly uniformly mixed, then special injector is loaded, the place enforcement encapsulant of sealing is being needed according to drawing requirement, continuous prodution can be realized, width, thickness and speed controlled, ensure that airtight quality, to the assembling parts of assembling be needed to get up after solidification 1h, hunt leak after solidifying 2h more under pressure, if there is no problem, (after solidification 3h, intensity can reach 100kpa can to reach certain intensity after continuing solidification 2-5h, high temperature resistant to about 1000 °), this intensity can ensure that in handling process, assembly is not moved, then move into heating reduction in electric furnace to test, reach probe temperature 700-800 DEG C, voltage after battery has reduced can reach about theoretical voltage 1.2V, illustrate that sealing effectiveness is very good.
Intensification test can be carried out after having solidified, almost there is no analyte in temperature-rise period, avoid the pollution to battery.
The above is only preferred embodiment of the present invention, is not restriction the present invention being made to any other form, and any amendment done according to technical spirit of the present invention or equivalent variations, still belong to the present invention's scope required for protection.
