1. A method of generating electrical power in a biological system, comprising:
- (a) inserting an anode and a cathode into the biological system comprising oxygen, wherein oxygen is present at the anode and the cathode;
(b) electrooxidizing a biochemical anode reductant on the anode in the presence of an anode enzyme; and
(c) electroreducing a biochemical cathode oxidant on the cathode in the presence of a cathode enzyme.

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.
