  • Publication number: 20090068544
    Abstract: There is disclosed a fuel cell having an anode and cathode and using either glycerol or biodiesel process waste (containing about 90% glycerol) as a fuel source to generate power and oxidize glycerol to oxidized fragments and carbon dioxide. More particularly, there is disclosed a liquid fuel cell incorporating a membrane-electrode assembly (MEA) wherein the electrocatalysts are embedded in or adjacent a polymeric conducting membrane with which they form the fuel cell body and glycerol or biodiesel process waste is oxidized to form the power source.
