DIRECT ELECTRON TRANSFER USING ENZYMES IN BIOANODES, BIOCATHODES, AND BIOFUEL CELLS

Bioanodes, biocathodes, and biofuel cells comprising an electron conductor, at least one anode enzyme or cathode enzyme, and an enzyme immobilization material. The anode enzyme is capable of reacting with a fuel fluid to produce an oxidized form of the fuel fluid, and capable of releasing electrons...

More Information
Summary:Bioanodes, biocathodes, and biofuel cells comprising an electron conductor, at least one anode enzyme or cathode enzyme, and an enzyme immobilization material. The anode enzyme is capable of reacting with a fuel fluid to produce an oxidized form of the fuel fluid, and capable of releasing electrons to the electron conductor. The cathode enzyme is capable of reacting with an oxidant to produce water, and capable of gaining electrons from the electron conductor. The enzyme immobilization material for both the anode enzyme and the cathode enzyme is capable of immobilizing and stabilizing the enzyme, and is permeable to the fuel fluid and/or the oxidant.
