英文摘要External humidifying system is generally needed for the fully hydration of membrane and catalyst layer, but it is considered as a barrier to PEMFC all the time. In this study, ultraviolet (UV) light was served as external stimulus to increase the wettability of anode which consists of photo-sensitive hygroscopic materials titanium oxide (TiO2). Under UV irradiation, water adsorbed on the photo-induced oxygen defects of TiO2 and transformed into surface hydroxyl groups. The generated hydroxyl groups furthered the back diffusion and decreased the charge resistance, which improved the performance at the low-humidity condition. The problems on the introduction of excessive hygroscopic materials are avoided by the new method. (C) 2014 Elsevier B.V. All rights reserved.
