Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to processing equipment for solid oxide fuel cells. Background technique [0002] Solid oxide fuel cell (SOFC) is composed of two electrodes and a solid electrolyte between the electrodes. It is an all-solid-state electrochemical power generation system that directly converts the chemical energy released by the redox reaction of fuel into electrical energy. SOFC It has the advantages of wide fuel application range, high energy conversion efficiency, fast kinetic process, and environmental friendliness. [0003] Propane is a common fuel, which can be obtained from crude oil, natural gas or refined oil, and has a high energy density, so it is a very suitable fuel for solid oxide fuel cells. [0004] Existing studies have shown that direct use of propane as fuel for solid oxide fuel cells has problems such as insufficient output performance, poor stability, and low fuel ...
