Abstract

Electrocatalyst layers in polymer electrolyte fuel cells (PEFCs) have complicated 3-dimensional microstructure, so that control and optimization of the structure are essential for higher cell performance. Carbon black supported cathode electrocatalyst is widely used, whilst carbon black support can be degraded through electrochemical oxidation on the cathode side. In this study, stable and electronic conductive Nb-doped SnO2 support deposited on conductive carbon nanotube (CNT) filler is considered as an alternative support material for increasing cell performance. Consequently, high current-voltage (I-V) performance and voltage cycle durability of membrane electrode assemblies (MEAs) using Nb-doped SnO2 supports deposited on CNTs are successfully demonstrated under the PEFC operational condition.
