Cofactor Modified Electrodes for Energy Transfer

  • Lemuel B. WingardJr.


Considerable interest has evolved over the past 10 years in the development of enzyme catalyzed devices for the transfer of chemical energy to electrical energy, i.e. enzyme fuel cells. Some of these devices have been of the direct type, where the enzyme is an integral part of one of the electrodes, while others have been of the indirect type, where an enzyme or microorganisms are used to convert a complex substrate for use in an inorganic fuel cell (1–6). Our interest has been in the direct type enzyme fuel cell, with the glucose oxidase-flavin cofactor system as a model anoidc catalyst. The objective of this paper is to discuss the chemical modification of the electrode surface, as an approach to improved enzyme catalyzed fuel cells, with special emphasis on flavin cofactor systems.
