Pt-loaded carbon catalysts, developed for polymer electrolyte fuel cell technology have been investigated by means of SANS to characterize the Pt cluster size distribution function. The investigated samples were prepared by depositing an electrocatalytic layer containing 0.5 mg cm-2Pt, on a composite carbon substrate. A Pt-free support, identical to the one used for the platinized samples, was used as a reference to obtain the SANS signal arising from the Pt clusters. Their size distribution function has been determined and compared with the results of transmission electron microscopy observations.
