Patent ID: 7807303

Claim:
A microbial fuel cell comprising: a cylindrically-shaped electrode assembly defining an axis and having a plurality of substantially aligned fibers, each of the fibers extending from a first end to a second end and having an outer surface, the electrode assembly including an anode segment and a bound segment, the bound segment defining a cell housing and the anode segment extending radially inward from the bound segment, the outer surfaces of the fibers of the anode segment being adapted for receiving a biofilm, the outer surfaces of the fibers of the bound segment being impregnated with a binder; a cathode substantially disposed on the axis of the electrode assembly; a membrane disposed intermediate the anode segment and the cathode, the membrane dividing the housing into first and second chambers, the first chamber being adapted for containing a fluid including a biomas, the second chamber being adapted for containing an oxygenated fluid; and an oxygen source adapted to oxygenate the fluid.
