Abstract
The behavior of a series of platinum‐base metal binary catalysts as anodes for the oxidation of fuel mixtures has been studied at 85° and 100°C with 85% phosphoric acid electrolyte. Platinum‐nickel catalysts show the best tolerance for carbon monoxide and the performance of catalysts with less than 25 w/o (weight per cent) nickel is much superior to that of platinum black. The effect appears to be related to the strength of bonding of chemisorbed carbon monoxide to the alloy surface.Keywords
