Potential difference between the electrodes (V) versus time-on-stream (h) for an n-hexadecane PAFC. Current density j = 0.04 mA/cm2. For the first and fifth experiment the values of the variables were as follows. Anode: water flow rate = 5.1 mL/h and n-hexadecane flow rate = 0.2 mL/h. Cathode: air flow rate = 245 mL/min. Temperature = 190°C. Pressure = 1 atm. For the sixth experiment, there was no water flow.
