Abstract
Official abstract text for this publication.
A series of binary and ternary Pt-alloys, that promote the important reactions for catalysis at an alloy surface; oxygen reduction, hydrogen oxidation, and hydrogen and oxygen evolution. The first two of these reactions are essential when applying the alloy for use in a PEMFC.
First claim
Opening claim text (preview).
What is claimed is: 1. A platinum (Pt) metal containing alloy composition useful as a catalyst, comprising: a film including a compound of Pt and at least one transition metal element A from group IVB or VB of the Periodic table, wherein: a structure of the compound is single phase, the compound comprises a Pt content of less than 50 Atomic percent (At. %), the compound exhibits a reversible electrochemical activity having a durability, and the reversible electrochemical a…
