Gas distribution base of SOFC power generation module integrated anode

Abstract

The invention provides a gas distribution base of an SOFC power generation module integrated anode. The gas distribution base comprises a substrate for placing a cell stack, wherein the substrate is provided with a plurality of transfer gas inlets and a plurality of transfer gas outlets; an opening of the gas distribution box is buckled on the substrate, so a gas inlet cavity is formed by the gas distribution box and the substrate, and the gas inlet cavity is communicated with an anode gas inlet of the cell stack through a transfer gas inlet; the gas collecting box is provided with an opening in one side, the opening of the gas collecting box covers the base plate and seals the gas distribution box, the gas collecting box, the base plate and the gas distribution box form a gas collecting cavity, and the gas collecting cavity is communicated with a waste gas outlet of the cell stack through a transfer gas outlet. According to the gas distribution base of the SOFC power generation module integrated anode provided by the invention, the gas collection box buckled on the substrate and the gas distribution box form the gas collection cavity to collect waste gas generated after a battery reacts, and heat in the waste gas is used for heating fuel gas conveyed into the gas inlet cavity formed between the gas distribution box and the substrate, so application cost of the battery is saved; energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of solid oxide fuel cells, in particular to a gas distribution base of an SOFC power generation module integrated anode. Background technique [0002] SOFC (Solid Oxide Fuel Cell) is a power generation device that directly converts chemical energy into electrical energy at medium and high temperatures. In the current use of solid oxide fuel cells, fuel gas is continuously fed into the anode side of the battery, for example: H 2 、CH 4 , synthesis gas, etc., oxygen or air is continuously fed into the cathode side of the battery, among which, CH 4 , Syngas is usually CH 4 After being compressed by the compressor, the syngas enters the mixer and reacts with the superheated steam generated in the steam generator to generate H 2 , after which the generated H 2 After the temperature is raised by the heater, it passes into the anode of the battery. Before entering the cathode, the air is compressed by the compr...
