Abstract
New methods for the use of waste products as input for other technologies are a constant subject of research efforts. One such product is waste engine oil. Due to the constantly increasing number of motor vehicles in the world, the recycling or application of engine oils for energy production purposes is currently of considerable importance. This paper contains research regarding the analysis of the electro-oxidation potential of waste engine oil, and thus the possibility of using such oil as a material in fuel cells. The research demonstrates the basic possibility of the electro-oxidation of this oil emulsion on a platinum electrode in an acid electrolyte (aqueous solution of H2SO4). It was shown that in the temperature range of 20–80 °C, the electro-oxidation of the waste engine oil emulsion occurred for all emulsion concentrations (0.005%, 0.010%, 0.030%, and 0.060% of the reactor volume). The maximum current density obtained in the measurements was 21 mA·cm−2 at the temperature of 60 °C (0.030% waste oil and 0.5 M electrolyte). Although this value is small, it encourages further research on the use of used engine oil for the direct generation of electricity.

Summary
Waste oils from gasoline and diesel engines were applied in the tests. The oils were obtained from a car service station. Measurements were made using the method of polarization electro-oxidation curves of the engine oil emulsion on a smooth platinum electrode in an acid electrolyte. The electro-oxidation of the detergent itself was tested (Syntanol DS10—concentration 0.005%, 0.010%, 0.030%, and 0.060% of the reactor volume) in order to ensure that the electric current was generated from the oil, and from the detergent. Measurements of the electro-oxidation of Syntanol DS-10 itself (without waste engine oil) in an acidic electrolyte (aqueous solution of H2SO4) were performed for various conoil) in an acidic electrolyte (aqueous solution of H2 SO4 ) were performed for various centrations of detergent at the temperatures of 20, 40, 60, and 80 °C.
