▎ 摘　　要

NOVELTY - Preparing cathode material comprises carbonizing lithium carbonate and iron oxide at 550-650°C to prepare lithium-iron oxide, adding oxidized graphene powder and carbonizing at 800-900°C. USE - Preparation method of cathode material is useful for molten carbonate fuel cells and used as chemical device for directly converting chemical energy of fuel into electric energy. ADVANTAGE - The molten carbonate fuel cell has good conductivity and stable electrical performance, and prolongs the service life of the cathode sheet and the fuel cell, and can satisfy for large scale industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: cathode material for molten carbonate fuel cells obtained by the above-mentioned method; Preparing cathode sheet for molten carbonate fuel cell; a molten carbonate fuel cell.
