Abstract

Electrocatalyst layer in polymer electrolyte fuel cells (PEFCs) has complicated 3D nanostructure, and control and optimization of the structure are essential for higher cell performance. Carbon black supported cathode catalyst is widely used, whilst carbon support can be degraded through electrochemical oxidation on the cathode side. The use of Nb-doped SnO2 supports for Pt electrocatalysts prevents support corrosion, while the use of carbon nanotube (CNT) based conductive fillers assists electronic transport in the electrocatalyst layers. High I-V performance of membrane electrode assemblies (MEAs) using stable SnO2 supports deposited on conductive CNT fillers is successfully demonstrated under the strongly acidic PEFC operational condition.
