Petroleum Diesel and Biodiesel Fuels Used in a Direct Hydrocarbon Phosphoric Acid Fuel Cell

Figure 9

Polarization curve for a hydrogen fueled PAFC: potential difference (V) between the electrodes versus current density (mA/cm2). Anode: hydrogen flow rate = 9.6 mL/min. Cathode: air flow rate = 245 mL/min. Temperature = 160°C. Pressure = 1 atm. Open circles are data points obtained after one TOS experiment with n-hexadecane. Solid circles are data points obtained after all TOS experiments with all diesel fuels. Open circles with “cross” signs are data points obtained after the degraded MEA had been regenerated during a 37-hour water treatment.
