| Abstract: |
SiO 2 -supported Pt composite catalyst was developed by ultrasonic technique, and applied as anode catalyst of PEMFC to improve the performance under non-humidified condition. Two different MEAs were prepared: one for adjusting Pt loading and the other for matching thickness to conventional Pt-only MEA. The characteristic tools, such as TEM, XPS, TGA, and FE-SEM were employed to characterize the composite catalyst and the MEAs thereof. The long-term performance of MEAs with the composite catalyst was evaluated under non-humidified and elevated temperature, and compared with that of Pt-only MEA. The self-humidifying ability of SiO 2 -supported Pt catalyst was examined by EIS technique. [ABSTRACT FROM AUTHOR] |
