Embodiment Construction

[0028] The tubular SOFC cell stack (such as image 3 shown) includes: fuel gas main intake pipe 1 (made of metal material), reforming catalyst chamber 2 (made of metal material), anode support tubular SOFC battery unit 3, gas distributor 7 (made of metal material into), fuel intake manifold (made of ceramic material), sealing layer 5 (made of glass), wire 4, etc.

[0029] The anode support tubular SOFC cell (such as figure 1 shown) is a tubular structure with one end closed and one end open, including an anode-supported electrolyte composite membrane tube 31, an electrolyte layer is formed on the periphery of the anode-supported electrolyte composite membrane tube 31, and a battery cathode 32 is formed on the periphery of the electrolyte layer; The closed end of the anode-supported electrolyte composite membrane tube 31 is formed with a battery connection pole 33 for connecting the cells in series. The battery connection pole 33 is formed directly on the anode-supported elect...

Abstract

The invention provides a tubular solid oxide fuel cell stack for portable power supply and its assembly method, which includes a power generation unit, a fuel main intake pipe, a fuel intake branch pipe, and a gas distributor, and the power generation unit is supported by a plurality of anodes Tubular SOFC battery units are connected in series, and each anode-supporting tubular SOFC battery unit is installed in the reserved hole of the gas distributor through the fuel inlet branch pipe. The fuel enters the gas distributor through the main fuel inlet pipe, and then passes through the fuel Inlet manifolds are assigned to each power generation unit. The invention realizes the assembly of the tubular solid oxide fuel cell stack, and provides a direction for the design of the portable electric stack adopting the anode support tubular SOFC cell.

Description

[0001] Technical field: [0002] The invention belongs to the field of fuel cell application, and relates to a tubular solid oxide fuel cell stack for portable power supply and an assembly method thereof. [0003] Background technique: [0004] Traditional portable power sources use secondary batteries as energy storage devices, such as lead-acid batteries, nickel-metal hydride batteries, and the like. The disadvantages of this type of products are low energy density, long charging time, and unfriendly environment. With the rapid development of electronic products such as mobile phones and portable computers, the requirements for power supply in terms of energy density and light weight are increasing day by day. Traditional batteries have become the main factor restricting the battery life of these products, and the demand for developing new portable power supplies is becoming increasingly urgent. [0005] As a new energy technology, fuel cells have many advantages such as hi...
