Abstract

The invention relates to a solid oxide fuel battery of taper-pipe anode support and battery group. Wherein, said battery comprises a porous anode support, a dense electrolyte film, and a porous cathode film. The porous anode support is in taper pipe shape whose one end mouth is large and another is small while the edge of small mouth is arc; the dense electrolyte film covers the outer edge of porous anode support; the cathode layer is at the upper layer of dense electrolyte between the arc edge of small mouth and the edge of large mouth. The battery group is formed by the outer edge of small mouth of said battery and the inner edge of big mouth of another inventive battery via the sealing material. The inventive battery has small size, high output power, easy production and the application of small SOFC electric pile. The cathode of said battery can be connected to the anode of another battery in series via sheathing one taper pipe on another taper pipe, with easy sealing.

Description

technical field [0001] The present invention relates to fuel cell technology, especially solid oxide fuel cell (or single cell) and a battery pack (or stack) of solid oxide fuel cell, specifically a conical tube type anode support Solid oxide fuel cell cells and stacks. Background technique [0002] A solid oxide fuel cell (SOFC) monomer (or single cell) is composed of an anode, a cathode, and an electrolyte sandwiched between the two electrodes. Area) is proportional, the open circuit voltage of each SOFC monomer is about 1V, and the working voltage is 0.7V. The SOFC battery pack (or electric stack) is composed of SOFC monomers through appropriate series and parallel connections. When SOFC works, fuel gas, such as hydrogen, needs to be provided to the anode, and oxidant gas, such as air, to the cathode. The fuel gas and oxidant gas generate electric current through electrochemical reaction, and the electric current passes through the external circuit and flows through th...
