Fuel cell of the type that uses, as a fuel, a carbon compound which undergoes electroxidation in said fuel cell. This cell comprises: a cathode (1), an electrolyte (10), and an anode (4). The anode has a first face that is fluid permeable and a second face which is in contact with the electrolyte. The second face comprises an atomic hydrogen transmissive membrane (5) made of an electrocatalytic metallic element which stores and diffuses hydrogen in atomic form. This membrane has an absorption side and an opposite insertion reaction side. There is also provided a method of generating electricity in a fuel cell as described generally and in any of the specific embodiments described above. This method comprises the sequential steps of: absorbing a hydrogen containing medium on the absorption side of the atomic hydrogen transmissive membrane, passing hydrogen in atomic form, through the membrane to the opposite insertion reaction side of this membrane, providing a carbon compound to this insertion reaction side, allowing the direct electroxidation reaction of the carbon compound on the insertion reaction side to give an electroxidation product, chemically reacting this with the hydrogen passed through the membrane to give a reduction reaction product, further electroxidizing this reduction reaction product to provide carbon dioxide, as the principal product of the complete electrochemical oxidation of the carbon compound; and drawing electricity generated thereby in said fuel cell from its cathode and anode. |
