摘要

Direct alcohol fuel cells have been attracting enormous research interest as power sources for vehiclesand portable electronic devices because alcohols are readily available, their storage and transport canbe easily handled with the existing fuel infrastructure, and they commonly have high mass-specific andvolumetric energy densities. Methanol is the most studied fuel for direct alcohol fuel cells becausemethanol is readily available, it is structurally simple, and has a promising electrochemical activity.However, several research groups have also reported the use of 2-propanol as a promising fuel. Thepotential advantages of utilizing 2-propanol as fuel are many such as it is relatively less toxiccompared to other alcohols, at low potentials it is less prone to anode poisoning, and it has betterresistance to crossover and cathode poisoning. The performance of the fuel cell for a particular catalystsystem is related to the cell conditions such as 2-propanol concentration, anode and cathode fuel flowrates, cell temperature and oxidant back pressure. This study was designed to study the effect of thedifferent cell operation conditions at three different levels and the interactions between thesecomponents by response surface methodology (RSM). We observed that the power density of the cellincreased with increase in molar concentration of 2-propanol and cell operation temperature, the2optimized conditions for the highest power density of 45 mW/cm by the RSM was found to be 1.5 Mo 2-propanol concentration, 80 C cell temperature, 9.22 ml/min 2-propanol flow rate, 596 ml/minoxygen flow rate and no back pressure for the oxidant, this is from amongst one of the best resultsreported in literature for direct 2-propanol fuel cell performance.
