NOVELTY - Ethanol direct oxidation and/or internal reforming involves using solid oxide fuel cell comprising mixed oxides and metal oxides such as cupric oxide, cuprous oxide, cerium(IV) oxide, yttrium oxide doped zirconium oxide and cerium aluminate. The mixed oxides and the metal oxides are supplied with fuel cell complexes such as ethanol or ethanol-water mixture for producing electricity, heat or water.    USE - Method for direct oxidation and/or internal reforming of ethanol and/or mixtures of ethanol and water by using solid oxides (claimed).    ADVANTAGE - The method provides direct oxidation or internal reformation of ethanol using multifunctional electrocatalytic anodes having specific features in a simple manner.    DETAILED DESCRIPTION - Ethanol direct oxidation and/or internal reforming involves using solid oxide fuel cell comprising mixed oxides and metal oxides such as cupric oxide, cuprous oxide, cerium(IV) oxide, yttrium oxide doped zirconium oxide and cerium aluminate of formula Ce1-xMxA1-yNyOs (I). The mixed oxides and the metal oxides are supplied with fuel cell complexes such as ethanol or ethanol-water mixture for producing electricity, heat or water.    M=strontium or calcium;    x and y=0-50; and    N=manganese, chromium or cobalt.    INDEPENDENT CLAIMS are also included for:    (1) a solid oxide fuel cell for direct oxidation and/or internal reforming of ethanol, for heating environment, water and equipment or for generating steam and for use in portable devices as games, computers, cell phones, palmtops, notebooks, laptops, other devices (generally powered by batteries or conventional cells) and hybrid electric vehicles including cars, buses, trucks and train, which comprises an anode made of multifunctional chemical-based mixed oxides and metal oxides; and    (2) a catalyst for direct oxidation and/or internal reforming of ethanol, which includes mixed oxides based on cerium aluminate.    DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron micrograph of particles of catalyst powder.
