Description

technical field [0001] The invention belongs to the field of solid oxide fuel cells-electrolytic cells, in particular to a kilowatt-level reversible solid oxide fuel cell-electrolytic cell testing system. Background technique [0002] Solid oxide fuel cell (SOFC) is an all-solid-state energy conversion device based on ceramic materials, which directly converts fuel chemical energy into electrical energy through high-temperature electrochemical oxidation reactions. Solid Oxide Fuel Electrolysis Cell (SOEC) is a high-temperature solid oxide electrolysis cell to decompose high-temperature water vapor into hydrogen and oxygen. It is an energy storage device that converts electrical energy and heat energy into chemical energy. The operation process of SOEC is the reverse process of SOFC . SOFC has the advantages of high efficiency, cleanness, recyclable high-temperature waste heat, and wide fuel adaptability. It is also one of the important technologies for realizing efficient a...
