Abstract

See full text

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.
