The colloidal tool-box approach for fuel cell catalysts: utilizing graphitized carbon supports

In the presented study we apply the “tool-box” approach for studying colloidal Pt nanoclusters as building blocks for polymer electrolyte membrane fuel cells (PEMFCs) catalysts utilizing graphitized carbon as support. In line with previous studies we concentrate on the influence of the carbon support on the degradation of PEMFC catalysts. It is demonstrated that a mild etching of the graphitized carbon support can lead to an improved stability under accelerated stress tests targeting carbon corrosion.
