Abstract
A fuel cell has an anode and a cathode with anode enzyme disposed on the anode and cathode enzyme is disposed on the cathode. The anode is configured and arranged to electrooxidize an anode reductant in the presence of the anode enzyme. Likewise, the cathode is configured and arranged to electroreduce a cathode oxidant in the presence of the cathode enzyme. In addition, anode redox hydrogel may be disposed on the anode to transduce a current between the anode and the anode enzyme and cathode redox hydrogel may be disposed on the cathode to transduce a current between the cathode and the cathode enzyme.
Claims21
An electrochemical cell for positioning in a biological system comprising oxygen, comprising:
- a substrate comprising a first face and a second face;
- an anode disposed on the first face of the substrate, wherein the anode comprises a crosslinked anode enzyme, mediator and polymer;
- and
- a cathode disposed on the second face of the substrate.
