Abstract
An aerobic microbial fuel cell anode electrode, a fuel cell using the anode, and methods of use. An anode electrode having a conductive exterior surface and having sufficient porosity to allow a fuel-bearing liquid flowing in a cavity within the anode to escape and to supply fuel to a biologically active microbe film grown on the exterior of the anode is situated in the fuel cell. When operated in an aerobic environment, such as water, the anode and a cathode can supply electrical power to a load without the need for a semi-permeable membrane between the anode and the cathode. Several embodiments in which the anode electrode is machined from a graphite block or cylinder are described. Conditions for growing the biologically active film and for operating the fuel cell are described.
