Evidence of Enhanced Low Temperature Water-Gas Shift Rate with Sodium Promoted Pt/Zirconia-Based Catalysts Discovered by Combinatorial Methods

For the successful commercialization of PEM fuel cells for portable power and transportation applications, there is a strong need to lower the amount of water-gas shift catalyst used within fuel processor for H2 production/purification. While most recent studies have improved the current understanding of water-gas shift catalysis, especially regarding structural-property relationships and catalytic mechanism, a highly active and stable catalyst has remained elusive. With the advent of combinatorial approaches, however, this situation is improving.
