A regenerative electrochemical cell system based on a fuel cell to oxidize methyl alcohol or other oxygenated hydrocarbons coupled with a regenerative cell to reduce carbon dioxide to form oxygenated hydrocarbons is disclosed. Methods to reversibly interconvert oxygenated hydrocarbons and carbon dioxide, to recycle carbon dioxide produced as a by-product of industrial processes, and to store and release electrical and chemical energy are also disclosed.

A liquid organic fuel cell is provided which employs a solid electrolyte membrane. An organic fuel, such as a methanol/water mixture, is circulated past an anode of a cell while oxygen or air is circulated past a cathode of the cell. The cell solid electrolyte membrane is preferably fabricated from Nafion.TM.. Additionally, a method for improving the performance of carbon electrode structures for use in organic fuel cells is provided wherein a high surface-area carbon particle/Teflon.TM.-binder structure is immersed within a Nafion.TM./methanol bath to impregnate the electrode with Nafion.TM.. A method for fabricating an anode for use in a organic fuel cell is described wherein metal alloys are deposited onto the electrode in an electro-deposition solution containing perfluorooctanesulfonic acid. A fuel additive containing perfluorooctanesulfonic acid for use with fuel cells employing a sulfuric acid electrolyte is also disclosed. New organic fuels, namely, trimethoxymethane, dimethoxymethane, and trioxane are also described for use with either conventional or improved fuel cells.
