Abstract
The invention provides a high-temperature sealing material for a solid oxide fuel cell. The high-temperature sealing material comprises the following raw materials in percentage by mass: 25-29 percent of calcium oxide, 20-24 percent of magnesium oxide, 2-4 percent of zinc oxide, 25-30 percent of silica, 11-16 percent of iron trioxide and 3-5 percent of boric oxide. Compared with the prior art, the high-temperature sealing material for the solid oxide fuel cell has good sealing performance.
Description
Technical field
The present invention relates to a kind of Solid Oxide Fuel Cell high temperature sealed knot material of sealed knot better performances.
Background technology
Along with the development of energy technology, the application of fuel cell is increasingly extensive.Solid Oxide Fuel Cell in hot operation adopts stupalith as electrolyte usually.Wherein, at the electrolyte both sides composite cathode of flat solid oxide fuel cell and the three-in-one structure of anode formation, by the sealed knot material battery unit and metallic interconnect materials are combined.Therefore the sealed knot performance of sealed knot material is for the performance outbalance of Solid Oxide Fuel Cell, especially whether the open circuit voltage after cycle operation repeatedly is stable, become an important indicator, and the sealed knot performance of existing Solid Oxide Fuel Cell high temperature sealed knot material is not enough, its repeatedly the open circuit voltage after the cycle operation descend larger.
Summary of the invention
The technical problem that the present invention mainly solves is that the sealed knot performance of present Solid Oxide Fuel Cell high temperature sealed knot material is not enough.
In order to solve the problems of the technologies described above, the embodiment of the invention discloses a kind of Solid Oxide Fuel Cell high temperature sealed knot material, described high temperature sealed knot material comprises the raw material of following mass percent:
Calcium oxide 25-29%,
Magnesium oxide 20-24%,
Zinc oxide 2-4%,
Silicon-dioxide 25-30%,
Ferric oxide 11-16%,
Boron oxide 3-5%.
In a preferred embodiment of the present invention, described high temperature sealed knot material comprises the raw material of following mass percent:
Calcium oxide 27%,
Magnesium oxide 22%,
Zinc oxide 3%,
Silicon-dioxide 28%,
Ferric oxide 15%,
