BACTERIAL AEROBIC ELECTRODE FOR ANODE OF A FUEL BATTERY WITHOUT REDOX MEDIATORS OR PROTON EXCHANGING MEMBRANE.

摘要

The invention relates to a biological electrode characterised in that it includes bacterial cells of the genus Acidiphilium sp., absorbed on the surface of a conductive electrode which operates under aerobic conditions. The electrode production method comprises the growth of the bacteria in aerobic solution at an acid pH in the presence of a carbonaceous conductive electrode and a nutrient, preferably glucose. The electrode can be used as an anode in a fuel cell.
