NOVELTY - The direct carbon fuel cell comprises anode, cathode and electrolyte in the middle portion. The electrolyte is sheet material obtained by pressing cerium oxide single phase or double phase composite material. The anode and cathode are thin plates obtained by pressing powder material. The anode material comprises composite material obtained by mixing carbon of biomass source, cleaned coal of coal source, green coke, petroleum, bitumen oil, carbon black or graphite. The cathode comprises lanthanum-strontium-manganese oxide and lanthanum-strontium-cobalt-iron oxide.    USE - Direct carbon fuel cell.    ADVANTAGE - The direct carbon fuel cell has excellent performance.    DETAILED DESCRIPTION - The direct carbon fuel cell comprises anode, cathode and electrolyte in the middle portion. The electrolyte is sheet material obtained by pressing cerium oxide single phase or double phase composite material. The anode and cathode are thin plates obtained by pressing powder material. The anode material comprises composite material (1-99 weight%) obtained by mixing carbon of biomass source, cleaned coal of coal source, green coke, petroleum, bitumen oil, carbon black or graphite. The cathode comprises lanthanum-strontium-manganese oxide (LaSrMnO), lanthanum-strontium-cobalt-iron oxide (LaSrCoFeO), samarium-strontium-cobalt oxide (SmSrCoO), copper-nickel-zinc oxide (CuNiZnO), lithium-copper oxide (LiCuO), copper-zinc oxide (CuZnO), lithium-cobalt oxide (LiCoO), lithium-manganese oxide (LiMnO), copper-cobalt oxide (CuCoO), copper-lithium-zinc oxide (CuLiZnO) or mixture of nickel oxide (in weight%) (0-99), cupric oxide (0-99), ferric oxide (0-99), manganese oxide (0-99), cobalt oxide (0-99) and stannic oxide (0-99). The carbon of biomass source is active carbon, block active carbon, granule active carbon, charcoal or plant ash carbon. The composite material is charcoal and active carbon composite, charcoal and coal composite, charcoal and graphite composite, charcoal and carbon black composite, carbon black and graphite composite, carbon black and coal composite, charcoal, coal and carbon black composite, or charcoal, coal, carbon black and graphite composite.
