Influence of Solvents on the Electroactivity of PtAl/rGO Catalyst Inks and Anode in Direct Ethanol Fuel Cell

Figure 15

Polarization and power density curve of PEM-DEFCs (a), (c), (e) and AEM-DEFCs (b), (d), (f) using the anode-coated different catalyst inks. Cathode: O₂ flow with a pressure of 2 atm. Anode: C₂H₅OH 2 M, 10 mL min⁻¹ (with PEM-DEFCs). C₂H₅OH 2 M + NaOH 1 M, 10 mL min⁻¹ (with AEM-DEFCs). Temperature: 50^oC.
