As fuel for fuel cells can be used various substances, but mainly fuel cells are powered by clear hydrogen (or hydrogen obtained from organic substances by reforming process). However, problems with the storage of hydrogen are the reason for the search of new fuels for fuel cells. Due to development of the renewable energy sources, the powering of fuel cells with bio-fuels is very important. Vegetable oil is an alternative fuel for diesel engines and for heating oil burners. Powering high efficiency power sources like fuel cells with renewable fuels (like canola oil) will allow development of renewable energy sources and elimination or reduce of toxic substances emissions. The paper presents the possibility of using canola oil as fuel for direct electricity production. The work shows possible electrooxidation of canola oil emulsion on a smooth platinum electrode in an solution of H2SO4. The resulting current density of canola oil electrooxidation reached the maximum level of 8 mA/cm2. So, the possibility of using canola oil as fuel for direct electricity production has been proved.
