Water-Gas Shift Catalysis

Develop water-gas shift (WGS) catalysts for on-board fuel processing that meet the DOE targets for performance [gas-hourly space velocity (GHSV) $30,000 h-1, CO conversion $90%, CO selectivity $99%], durability [lifetime >5000 h], and cost [<$1/kWe]. Eliminate the drawbacks of commercial WGS catalysts, CuZn and FeCr oxides, for on-board fuel processing, including the need for well-controlled in situ activation, the loss of activity due to temperature excursions, and the need to sequester the catalysts during shutdown to prevent deactivation.
