The subject invention is a catalyst consisting of an oxide or mixed oxide
support and bimetallic catalytically active compounds. The supporting
oxide can be a single oxide, such as Al.sub.2O.sub.3; it also can be a
mixture of oxides, such as Y.sub.2O.sub.3 stabilized ZrO.sub.2 (YSZ),
Al.sub.2O.sub.3 with CeO.sub.2, Al.sub.2O.sub.3 with YSZ and others. The
bimetallic compounds, acting as active components, are selected from
platinum, and ruthenium, prepared in an appropriate ratio. The catalyst
is used in the steam reforming of hydrocarbons to produce hydrogen for
applications such as polymer electrolyte membrane fuel cells.
