US Patent:

20080292912, Nov 27, 2008
Filed:

Jul 23, 2008
Appl. No.:

12/177962
Inventors:

Bruce Logan - State College PA, US
Shaoan Cheng - State College PA, US
Assignee:

The Penn State Research Foundation - University Park PA
International Classification:

H01M 8/16
H01M 8/04
US Classification:

429 2, 429 13
Abstract:

Methods of improving a performance parameter of a microbial fuel cell are provided according to embodiments of the present invention which include heating an electrode and exposing the heated electrode to ammonia gas to produce a treated electrode characterized by an increased positive surface charge on the electrode surface. Improved performance parameters include increased maximum power density, increased coulombic efficiency, increased volumetric power density and decreased microbial fuel cell operation time to achieve maximum power density

US Patent:

20090317882, Dec 24, 2009
Filed:

Jun 22, 2009
Appl. No.:

12/488951
Inventors:

Shaoan Cheng - State College PA, US
Bruce Logan - State College PA, US
Assignee:

The Penn State Research Foundation - University Park PA
International Classification:

C12P 5/02
C12N 1/00
US Classification:

435167, 435243
Abstract:

Increasing competition for fossil fuels, and the need to avoid release carbon dioxide from combustion of these fuels requires development of new and sustainable approaches for energy production and carbon capture. Biological processes for producing methane gas and capturing carbon from carbon dioxide are provided according to embodiments of the present invention which include providing an electromethanogenic reactor having an anode, a cathode and a plurality of methanogenic microorganisms disposed on the cathode. Electrons and carbon dioxide are provided to the plurality of methanogenic microorganisms disposed on the cathode. The methanogenic microorganisms reduce the carbon dioxide to produce methane gas, even in the absence of hydrogen and/or organic carbon sources.
