We find that the maximum aerobic mini-MFC power without the addition of exogenous mediators was 0.40 mW, a 33% decrease when compared with an anaerobic DSP10 culture (0.6 mW) operating in the mini-MFC. This decrease is most likely due to the presence of dissolved oxygen in the anode chamber that scavenges electrons to form water, thereby reducing the number of electrons donated to the anode. Aerobic power and current density at maximum power using the true surface area of the anode (611 cm2) were calculated to be 6.5 mW m-2 and 13 mA m-2. The power density rises to 2.0 W m-2 and 330 W m-3 when calculated using the cross-sectional area and volume of the device (2 cm2, 1.2 cm3). The Coulombic efficiency was also reduced from 11 to 5% when using the aerobic versus anaerobic culture. Similar results were found when the external mediator anthraquinone-2,6-disulfonate (AQDS) was added to the aerobic culture, resulting in a maximum power of 0.54 mW, a 37% drop in power when compared to the anaerobic mediated system.", "publicationTitle": "Journal of Power Sources", "publisher": "", "place": "", "date": "March 20, 2007", "volume": "165", "issue": "2", "section": "", "partNumber": "", "partTitle": "", "pages": "591-597", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1016/j.jpowsour.2006.10.026", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/B6TH1-4MBBYTP-4/2/c57bd53c185be44c76b6cc893d7715c4", "accessDate": "2010-05-04T03:15:08Z", "PMID": "", "PMCID": "", "ISSN": "0378-7753", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "0000", "rights": "", "extra": "", "tags": [ { "tag": "Aerobic", "type": 1 }, { "tag": "Anaerobic", "type": 1 }, { "tag": "Mediated", "type": 1 }, { "tag": "Microbial fuel cell (MFC)", "type": 1 }, { "tag": "Miniature microbial fuel cell (mini-MFC)", "type": 1 }, { "tag": "Shewanella oneidensis", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-05-04T03:15:29Z", "dateModified": "2010-06-28T04:16:33Z" } }, { "key": "5ZNBKJ27", "version": 1, "library": { "type": "group", "id": 17122, "name": "Microbial Fuel Cell", "links": { "alternate": { "href": "https://www.zotero.org/groups/microbial_fuel_cell", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/17122/items/5ZNBKJ27", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/microbial_fuel_cell/items/5ZNBKJ27", "type": "text/html" } }, "meta": { "createdByUser": { "id": 236055, "username": "Azen", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/azen", "type": "text/html" } } }, "creatorSummary": "Borole et al.", "parsedDate": "2008", "numChildren": 0 }, "data": { "key": "5ZNBKJ27", "version": 1, "itemType": "journalArticle", "title": "A microbial fuel cell operating at low pH using the acidophile Acidiphilium cryptum", "creators": [ { "creatorType": "author", "firstName": "Abhijeet", "lastName": "Borole" }, { "creatorType": "author", "firstName": "Hugh", "lastName": "O’Neill" }, { "creatorType": "author", "firstName": "Costas", "lastName": "Tsouris" }, { "creatorType": "author", "firstName": "Scott", "lastName": "Cesar" } ], "abstractNote": "Abstract For the first time, a microbial fuel cell has been developed using an acidophile, Acidiphilium cryptum, as the anode biocatalyst.
