Abstract

The invention discloses a connector of a self-sealing flat plate type solid oxygenated fuel cell and a preparation method. The connector comprises a metal connecting pole and a porous metal layer, wherein a gas passage is arranged on one side of the metal connecting pole; a groove is formed in the side, provided with the gas passage, of the metal connecting pole, and the porous metal layer is arranged in the groove. A connector and supporting metal integrated structure of the self-sealing flat plate type solid oxygenated fuel cell is prepared through a method that a shelter is finally removed through sheltering and powder metallurgy on one side of the interior of the connecting pole. A cell functional layer is prepared on the integrated structure, self-sealing of the cell can be realized, the manufacturing technique of a cell stack can be greatly simplified, the cell stack does not need the introduction of any additional sealing structure, the problem that the flat plate type solid oxygenated fuel cell is sealed is overcome, the manufacturing cost of the cell is reduced, and the commercial popularization of the cell is facilitated.

Description

technical field

[0001] The invention relates to the field of energy technology, in particular to an integrated structure of a connecting body and a supporting metal of a self-sealing flat solid oxidation fuel cell and a preparation method thereof. Background technique

[0002] Solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) belongs to the third-generation fuel cell, which is an all-solid-state chemical energy that directly converts the chemical energy stored in fuel and oxidant into electrical energy in an efficient and environmentally friendly manner at medium and high temperatures. power generation device. The main components of a solid oxide fuel cell are electrolyte, anode or fuel electrode, cathode or air electrode, and connector or bipolar plate. The working principle of solid oxide fuel cells is the same as that of other fuel cells, and is equivalent to the "reverse" device of water electrolysis in principle. Its single cell is composed of anode, cathode and sol...
