PCT No. PCT/SE82/00059 Sec. 371 Date Dec. 2, 1982 Sec. 102(e) Date Dec. 2, 1982 PCT Filed Mar. 8, 1982 PCT Pub. No. WO82/03729 PCT Pub. Date Oct. 28, 1982.Electrodes for the electrochemical regeneration of the co-enzymes, NADH, NADPH or analogs thereof. The electrode surface has been modified by adsorbing thereto a condensed aromatic ring system comprising at least three, preferably four or more, condensed aromatic rings. A method of preparing the electrodes is also described, in which a condensed aromatic ring system is adsorbed to the surface of carbon or a graphitic material. Finally, there is described the use of said electrodes for the electrochemical regeneration of co-enzyme in biochemical, microbiological or biochemical processes as the anode in biochemical fuel cells or for analysis in systems utilizing co-enzyme-dependent enzyme.
