First Claim
Patent Images
1. A bacterial fuel cell comprising:
- at least one anode and at least two cathodes in liquid communication with a liquid to be treated, said at least one anode being separated from said at least two cathodes by at least first and second electrically insulating, water-side spacers and said at least one anode and said at least two cathodes being electrically connected across an external load; and
said at least one anode and said at least two cathodes being wound together generally in a spiral configuration together with at least a third, air side spacer providing a separation between adjacent layers of the spiral, a layer of the spiral being defined by at least one anode and its flanking cathodes, whereinthe air-side spacer has a thickness to permit airflow passageway between layers of the spiral; and
the water side spacers define a separation between the anode and flanking cathodes through which the liquid to be treated flows; and
whereinsealing is provided between said at least two cathodes, whereby said at least one anode is enclosed inside an enclosure including said sealing and said at least two cathodes.
