Abstract
An electrocatalytic material comprises an alloy of platinum with another element, supported on a conductive carbon support, the platinum loading being at 20 to 60 wt % and the ECA of the alloy being greater than 35 m.sup.2 /g, is especially suitable for use in phosphoric acid fuel cells, and demonstrates unexpectedly high performance with high Pt loadings.
