Development of Anodic Materials with Elevated Hydrogen Sulfide Tolerance for HT-PEMFCs Using Reformat

Abstract

The use of PEMFCs at low or high temperature represents a promising alternative to combustion engines for numerous applications, even if pure hydrogen is not an option as fuel. Unfortunately the presence of C-species and in particular S-species can lead to significant deactivation of the active materials used as electrodes. This is observed as a loss in the performance of the fuel cell. In order to diminish this problem the development of alternatives Pt-based electrodes has been extensively studied. This study presents the development and evaluation of alternative Pt-based electrodes which exhibit a significantly increased resilience against H2S poisoning.
