| The availability of fuel processing catalysts that are active in the presence of sulfur will provide considerable flexibility to fuel cell system designers, especially when infrastructure fuels are targeted for use. NexTech Materials has established a suite of water gas shift catalysts that are active in the range of 400 to 450°C and provide reasonable stability in H2S (10-50 ppm). These catalysts were developed for use with sulfur tolerant hydrogen separation membranes in a logistic fuel processing system that is being developed and demonstrated for the Navy. NexTech also has demonstrated a single hydrocarbon reforming catalyst formulation that is resistant to sulfur and active for a number of reactions, including steam reforming, partial oxidation, autothermal reforming, and carbon dioxide reforming reactions. These multi-functional catalysts are not completely immune to sulfur, but provide stable performance during reforming of hydrocarbons in the presence of H2S. Such catalysts are targeted for use in near-anode (internal) reforming in solid oxide fuel cell stacks. |
