摘要： The invention provides systems and methods for generating organic compounds using carbon dioxide as a source of carbon and electrical current as an energy source. In one embodiment, a reaction cell is provided having a cathode electrode and an anode electrode that are connected to a source of electrical power, and which are separated by a permeable membrane. A biological film is provided on the cathode. The biological film comprises a bacterium that can accept electrons and that can convert carbon dioxide to a carbon-bearing compound and water in a cathode half-reaction. At the anode, water is decomposed to free molecular oxygen and solvated protons in an anode half-reaction. The half-reactions are driven by the application of electrical current from an external source. Compounds that have been produced include acetate, butanol, 2-oxobutyrate, propanol, ethanol, and formate.

摘要： 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.
