                      polymer electrolyte membrane fuel cell (HT-PEFC)
                      polybenzimidazole (PBI) based membrane electrode assemblies
                      (MEAs) is undertaken utilizing the design of experiments
                      (DOE) method, a very valuable statistical optimization
                      method, much underutilized in fuel cell research. Single
                      cell voltages are examined as a response (target variable)
                      at two levels (high and low) of four factors (controlled
                      variables); anode and cathode stoichiometry, operating
                      temperature and current density. This yields a two-level,
                      four factor (24) full factorial DOE. The data is used to
                      form a linear regression model for each MEA, which is in
                      turn utilized to predict the cell voltage at random values
                      within the selected ranges of the four factors for
                      validation. The main effects and two factor interactions of
                      each factor are compared to determine their effect on the
                      cell voltage and the underlying physics is examined to
                      determine the best performing MEAs. The PBI based MEA has a
                      much higher tolerance to carbon monoxide (CO) in the fuel
                      stream in comparison with Nafion based MEAs due to the
                      different proton conducting mechanism as well as a higher
                      operating temperature, thus enabling reliable operation of
                      HT-PEFC stacks with reformate containing upto $3\%$ CO.},
