Filed:

Oct 1, 2008

Appl. No.:

12/243650

Inventors:

Daniel R. Noguera - Madison WI, US
Timothy J. Donohue - Madison WI, US
Marc A. Anderson - Madison WI, US
Katherine D. McMahon - Madison WI, US
Isabel Tejedor - Madison WI, US
Rodolfo E. Perez - Madison WI, US

International Classification:

H01M 8/16

US Classification:

429 2

Abstract:

Devices and methods for generating electricity utilizing a light-powered microbial fuel cell that includes a light-admitting reaction chamber containing a biological catalyst, such as a photosynthetic bacteria, in a growth medium, an anode and cathode disposed upon or within the reaction chamber, and a conductive material in electrical communication between the anode and cathode. The anode includes an oxidation catalyst, while the cathode includes a reduction catalyst that is accessible to oxygen gas. Preferably, the devices and methods utilize a single light-admitting chamber within which both cathodic and anodic reactions take place.
