Abstract

Chloride residues on the surface of fuel cell catalysts are known to decrease the catalytic activity, especially for O2 reduction. Using Armand's ligand, which contains the chloride free DCTA anion, for the colloidal stabilisation of nanoscopic Pt and PtRu catalysts precursors (<2 nm size) leads to PEMFC and DMFC catalysts with improved activity compared to commercial E-TEK catalysts as evidenced by both methanol oxidation and CO-stripping voltametric studies.
