Enzymatic Biofuel Cells

An Enzymatic Biofuel Cell is a specific type of fuel cell which uses biocatalysts to convert energy stored within chemicals into electrical energy. Enzymes are normally used to catalytically oxidise the fuel at the anode and reduce the ensuing oxidant at the cathode. The specificity of the enzyme reactions at the anode and cathode electrodes of an enzymatic fuel cell eliminates the need for other components required forconventional fuel cells, such as a case and membrane. To date, no commercial enzymatic biofuel cell exists, mainly due to poor stability and power output.
