Voltage Readjustment Methodology According to Pressure and Temperature Applied to a High Temperature PEM Fuel Cell

The operating conditions can have uncontrolled effects on the voltage of a High-Temperature Proton Exchange Membrane Fuel Cell (HT-PEMFC). For instance, HT-PEMFC be used at ambient pressure, i.e., without having back pressure regulator. In this case, variation in atmospheric directly affects pressures inside fuel cell, which induces variation. Moreover, transient phases, several coupled phenomena an effect voltage. example, following change current point, thermal cell vary, and temperature stabilization then leads to This article introduces readjustment method for compensate variations that are undergone decouple their effects. methodology is based realization design experiments characterize sensitivity ([1; 1.5 bar]) ([120; 180 °C]) between 0.2 1 A/cm2 Advent PBI MEA (formerly BASF Celtec®-P 1100 W). data obtained allowed identifying empirical model takes into account aging caused by experiment. Finally, criticized before proposing alternative method.
