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

Figure 7

Potential difference between electrodes (V) as a function of time (h) obtained with a PAFC. Anode: water flow rate = 5.1 mL/h, n-hexadecane flow rate = 0.2 mL/h. Cathode: air flow rate = 245 mL/min. Temperature = 190°C, pressure = 1 atm, with an H₂O/C₁₆H₃₄ ratio = . The numbers on the top of each line represent different current densities.
