Description: This report summarizes the last elements of work conducted in this program prior to its termination at the end of FY `87. The work was primarily an analysis of a fuel cell electrocatalyst using electron microscopy. The catalyst was a three component system containing Pt-Co-Ni (3:2:2 atomic ratios) dispersed on an amorphous carbon support in unknown phases, supplied to us by Giner Inc. (designated as their sample no. G82-5-19). The preparation of this catalyst is proprietary, (patent pending). Our objective was to analyze the catalyst by a variety of techniques to determine, to the greatest extent possible, the distribution of the three elements on the carbon support along with identification of their chemical states and phases.
