Abstract
One type of genuine fuel cell that does hold promise in
the long-term is the biological fuel cell. Unlike conventional
fuel cells, which employ hydrogen, ethanol and
methanol as fuel, biological fuel cells use organic products
produced by metabolic processes or use organic
electron donors utilized in the growth processes as fuels
for current generation. A distinctive feature of biological
fuel cells is that the electrode reactions are
controlled by biocatalysts, i.e. the biological redoxreactions
are enzymatically driven, while in chemical
fuel cells catalysts such as platinum determine the
electrode kinetics. This article provides a brief introduction
to biological fuel cells along with their envisaged
applications.
