With the aim of overcome the carbon supports of high temperature Proton Exchange Membrane Fuel cells (HT-PEMFC) electrodes, two novel non-carbonaceous support based on SiC have been assessed, SiC and SiCTiC. 40% wt. Pt was successfully deposited on them and they were physicochemical and electrochemically characterized. Both catalysts on SiC based materials showed a very high electrochemical stability in the half cell experiments in comparison with Pt on carbon support, showing a lower degradation rate of the electrochemical surface area (ECSA). Membrane Electrode Assemblies (MEAs) were prepared with the different catalysts and tested in a single cell (25 cm(2)) operated at 160 degrees C. The Pt/SiCTiC showed a good performance and the highest stability in the fuel cell tests carried under the same operation conditions. (C) 2016 Elsevier B.V. All rights reserved.
