Title: SHIFT REACTOR FOR DIRECT FUEL CELL HYDROGEN SYSTEM
Abstract:
A multi-stage shift reactor includes a vessel (1) having an inner chamber configured to contain a first shift catalyst (54), the first shift catalyst configured to receive anode exhaust gas form a fuel cell and to output a first shifted gas, and an outer chamber annularly disposed about the inner chamber and configured to contain a second shift catalyst (64), the second shift catalyst configured to receive the first shifted gas and output a second shifted gas. The shift reactor further includes a water injection port (56) downstream from the inner chamber and packing (58) between the water injection port and the outer chamber, the packing configured to prevent liquid water from passing therethrough.
