Subin et al. [184] also conducted several experiments on fuel cell performance at varyingoperational conditions. From Fig. 18, it is observed that the fuel cell performance increases appreciably between cell operating temperatures of 45 Ce50 C. When the fuel cell is operated at cell operating temperature of 45 C, the performance is reduced at lowcurrent densities. This is because the electrochemical kinetics at this cell operating temperature is poor. The performance of the fuel cell at higher current density is observed to be better at cell operating temperature of 45 C compared to that of 50 C. At 50 C, there is decrease in fuel cell performance at high current density due to many factors. The researchers argued that flooding, dehydration of the membrane electrode assembly and reactant starvation, all directly related to water management in the fuel cell, were some ofthe reason for this fuel cell characteristics.
