Title

In Situ And Ex Situ Characterization Of Carbon Corrosion In Pemfcs

Abstract

Carbon corrosion is an important degradation mechanism that impairs PEMFC performance through destruction of catalyst connectivity, collapse of pore structure, and loss of hydrophobic character. In this study, carbon corrosion was quantified in situ by measurement of carbon dioxide in fuel cell exhaust gases through non-dispersive infrared spectroscopy (NDIR). Performance degradation was also studied by a DOE protocol for catalyst support accelerated stress testing. Finally, changes in gas diffusion layer and microporous layer carbon surfaces were observed through an ex situ aging procedure. ©The Electrochemical Society.
