Abstract

The invention provides a solid oxide fuel cell power generation system, comprising a solid oxide fuel cell stack and a pressure vessel, wherein the pressure vessel is provided with first, second, third and fourth pipelines for gas circulation with the outside under sealed conditions; and in a working state, the solid oxide fuel cell stack is placed in the pressure vessel, an oxidizing gas is introduced into the pressure vessel, a fuel gas is introduced into an anode channel of the battery simultaneously, and the battery is discharged under high pressure. The power generation system has high airtightness, the cathode side can be exposed, no gas channel is required, the pressure limit of the fuel cell is broken, and the power generation efficiency is improved.

Description

technical field [0001] The technical field of the solid oxide fuel cell of the present invention, in particular relates to a solid oxide fuel cell power generation system and its usage method. Background technique [0002] Solid Oxide Fuel Cell (SOFC) is an energy conversion device that can directly convert chemical energy into electrical energy. SOFC has the advantages of high energy conversion efficiency and environmental friendliness, so it has received extensive attention from researchers. [0003] The basic structure of SOFC includes a porous anode, a porous cathode, and a dense electrolyte layer. After the fuel is fed into the anode and the oxidant gas is fed into the cathode, an electrochemical reaction will occur at the three-phase interface between the electrolyte and the electrode to generate electrons, and the electrons will form a discharge circuit through an external circuit to generate electricity and heat. [0004] The core component of the solid oxide fuel ...
