dc.description.abstract | In this study, the oxygen reduction reaction (ORR) performance improvement of polymer electrolyte membrane fuel cells (PEMFCs) is investigated using a low magnetic field density. The transient performance of a PEMFC using a magnetic field (MF-PEMFC) was measured and analyzed by varying the cell temperature, voltage, relative humidity, and pre-humidification time. Based on the results, the mechanism of the performance improvement of MF-PEMFC was revealed, and a strategy to maximize its performance was proposed. Enhanced oxygen mobility by a magnetic field led to a higher ORR performance and membrane humidification was accelerated by the vigorous ORR. The performance improvement of MF-PEMFC was more substantial under unfavorable membrane humidification conditions such as high temperature and low operating voltage. The maximum performance improvement of MF-PEMFC compared to that of normal PEMFC was 8.6% at 40% relative humidity, 0.30 V voltage, and 80 celcius cell temperature due to an enhanced self-humidification effect. In addition, the maximum performance improvement and stability of MF-PEMFC were obtained with the proper pre-humidification time. In conclusion, using a magnetic field can improve the performance and stability of PEMFCs under unfavorable operating conditions. | - |
