1. A fuel cell consisting essentially of:
- an anode;
anode enzyme disposed on the anode, the anode being configured and arranged for electroxidizing an anode reductant in the presence of the anode enzyme;
a cathode spaced from the anode; and
cathode enzyme disposed on the cathode, the cathode being configured and arranged for electroreducing a cathode oxidant in the presence of the 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.
