Abstract:
1. A biofuel cell for generating electricity using a fuel fluid comprising: a non-conducting substrate; a cathode supported by the substrate and capable of a reaction to reduce an oxidant in the presence of electrons to form water; an anode supported by the substrate and capable of a reaction to oxidize the fuel fluid; at least one of the anode and cathode including an enzyme for use in carrying out its respective reaction; and either (i) at least one of the anode and cathode being formed for flow of the fuel fluid and/or oxidant therewithin for use in producing an electrical current; or (ii) at least one of the anode and cathode comprising a width less than about 200 μm and at least one surface having an irregular, three dimensional topography capable of inducing convective flow of the fuel fluid and/or oxidant over said surface.
