Title: Shift reactor for direct fuel cell hydrogen system

Abstract

A multi-stage shift reactor includes a vessel having an inner chamber configured to contain a first shift catalyst, 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, 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 downstream from the inner chamber and packing between the water injection port and the outer chamber, the packing configured to prevent liquid water from passing therethrough.
