Abstract:
An electrochemical device converts carbon dioxide to a formic acid reaction product. The device includes an anode and a cathode, each comprising a quantity of catalyst. The anode and cathode each have reactant introduced thereto. A cation exchange polymer electrolyte membrane and an anion exchange polymer electrolyte membrane, are interposed between the anode and the cathode, forming a central flow compartment where a carbon dioxide reduction product, such as formic acid, can be recovered. At least a portion of the cathode catalyst is directly exposed to gaseous carbon dioxide during electrolysis. The average current density at the membrane is at least 20 mA/cm 2 , measured as the area of the cathode gas diffusion layer that is covered by catalyst, and formate ion selectivity is at least 50% at a cell potential difference of 3.0 V.

Claim (Index 39):
The electrochemical device of  claim 36 , wherein said anion exchange polymer of said cathode catalyst layer further comprises a copolymer of at least one of methyl methacrylate and butylacrylate.
