On the Use of Potential Denaturing Agents for Ethanol in Direct Ethanol Fuel Cells
Figure 6
Cyclic voltammetry of ethanol solutions containing a mixture of ETBE and Bitrex at a PtSn catalyst in 0.5 M H2SO4 (a) and at a PdCoFe catalyst in 0.1 M KOH (b). Base electrolyte (line), 1 M ethanol (dashed), and 1 M ethanol + 0.24 wt.-% ETBE /0.5 mg L−1 Bitrex (dotted). Scan rate 50 mV s−1.
