Figure 7
Fuel cell tests of pure ethanol (grey), ethanol solutions containing a mixture of ETBE and Bitrex (black) in acidic (a) and alkaline environment, (b). (a) PtSn + PtRu anode (3.68 mg metal cm−2), Nafion 115 membrane, and PtCo cathode (2.67 mg metal cm−2). 1 mL min−1 aqueous 1 M ethanol, 1.4 L min−1 air, 50°C. (b) Acta Hypermec3 anode, Fumasep FAA membrane and Acta Hypermec cathode. 1 mL min−1 10% ethanol + 10% KOH, 250 mL min−1 air, 50°C.
