n-Hexadecane Fuel for a Phosphoric Acid Direct Hydrocarbon Fuel Cell

Figure 3

Polarization curve for a hydrogen fueled PAFC: potential difference between the electrodes (Volts) and current density (mA/cm²). Open diamonds are data obtained on a new MEA. Open squares are data obtained on an MEA that had been conditioned in previous experiments with low molecular weight hydrocarbons (ethylene, propane). Anode: hydrogen flow rate = 9.6 mL/h. Cathode: air flow rate = 245 mL/min. Temperature = 160°C. Pressure = 1 atm.
