On/off cycling test of low-temperature PEM fuel cell at fully humidified conditions
Popis výsledku v původním jazyce
Accelerated stress testing is one of the most used approaches to characterize the performance and the degradation of the membrane electrode assembly (MEA) in low-temperature hydrogen polymer electrolyte membrane fuel cells (PEMFC). A standard JRC on/off testing procedure was used to characterize two sets of commercial MEAs, by ElectroChem and by PaxiTech, respectively. Performance characteristics prior to and after the on/off procedure were measured. Thechanges in the resistivity of the MEA were examined by electrochemical impedance spectroscopy (EIS). The EIS data were analyzed and interpreted by a suitable equivalent circuit that consisted of a resistor and the Voigt’s structure in series with constant phase elements. Water on the anode side and the cathode side of the PEMFC was collected during the on/off procedure. The fluoride emission rate was determined from the collected water to obtain information about the chemical degradation of the MEA samples.
