In this study, combinatorial libraries were fabricated by using multi-layer sputtering method to have 63 different ternary compositions. The combinatorial libraries were quickly evaluated by using multichannel multielectrode analyzer for methanol electro-oxidation and oxygen electro-reduction reaction activities. Promising compositions identified by the combinatorial method were also synthesized in their powder version for detailed electrochemical testings. Various ternary systems including Pt-Ru-Cu, Pt-Ni-Cr, and Pt-Co-Cr were evaluated for the methanol electro-oxidation reaction. In addition, oxygen electro-reduction activity of the Pt-Co-Cr catalysts was alsoinvestigated as a promising fuel cell cathode candidate. |
