Patent number: 9029025Abstract: A method and an apparatus is provided for increasing biofilm formation and power output in microbial fuel cells. An anode material in a microbial fuel cell has a three-dimensional and ordered structure. The anode material fills an entire anode compartment, and it is arranged to allow fluid flow within the anode compartment. The power output of microbial fuel cells is enhanced, primarily by increasing the formation and viability of electrogenic biofilms on the anodes of the microbial fuel cells. The anode material in a microbial fuel cell allows for the growth of a microbial biofilm to its natural thickness. In the instance of members of the Geobacteraceae family, the biofilm is able grow to a depth of about 40 microns.Type: GrantFiled: April 24, 2012Date of Patent: May 12, 2015Assignee: HRL Laboratories, LLCInventors: Tina T.

Patent number: 8349517Abstract: A method of coating a surface of a fuel cell plate is disclosed herein, and involves forming a sol gel mixture by mixing a weak acid and a composition including at least two metal oxide precursors. One of the metal oxide precursors is configured to be hydrolyzed by the weak acid to form a mixed metal oxide framework with an other of the metal oxide precursors having at least one organic functional group that is not hydrolyzed by the weak acid. The mixture is applied to the surface, and is condensed by exposure to air at least one predetermined temperature and for a predetermined time. The sol gel mixture is immersed in water at a predetermined temperature and for a predetermined time to form a porous, hydrophilic, and conductive film on the surface.Type: GrantFiled: April 23, 2009Date of Patent: January 8, 2013Assignee: GM Global Technology Operations LLCInventors: Wen Li, Ping Liu, Jennifer J.

Patent number: 8097234Abstract: A capsule having a hydrogen gas permeable shell with solid-state hydride material, such as hydrogen rich LiAlH4, Li3AlH6, and/or AlH3 encapsulated therein. The hydrogen gas permeable shell has pores that are between about 1 nm to about 150 ?m in diameter to allow hydrogen gas to be extracted from the capsule. After passing the capsule through a hydrogen extraction zone, the capsule containing the spent solid-state hydride material is removed and is sent to recycling, wherein the capsule is opened to remove the spent solid-state hydride material, and the spent solid-state hydride material is rehydrogenated and repacked in a hydrogen gas permeable shell. The shell of the spent solid-state hydride material can be recycled and reused to make new shells.Type: GrantFiled: March 25, 2011Date of Patent: January 17, 2012Assignee: HRL Laboratories, LLCInventors: John J.

Patent number: 7993797Abstract: A membrane-electrode assembly in a polymer electrolyte/proton exchange membrane fuel cell includes the electrodes (anode and cathode), with a thin layer of catalyzed conductive support particles bonded to either side of the membrane. Where the polymer membrane comprises pendant chains of fluorinated carbon atoms with mobile proton containing terminal groups, proton conductivity with the catalyst particles is improved by chemically attaching like pendant chains to carbon atoms at surfaces of carbon particles. In certain implementations, an amino aryl perfluorinated sulfonic acid precursor is prepared. This precursor is converted to an aryl diazonium cation in the presence of carbon particles. The diazonium cation is reduced to the aryl radical which reacts with carbon atoms of the carbon substrate.Type: GrantFiled: July 10, 2007Date of Patent: August 9, 2011Assignee: GM Global Technology Operations LLCInventors: Tina T.
