Abstract

Embodiments of a compact pressure swing reformer are disclosed. Certain embodiments have a construction comprising multiple rotating reformer beds, high temperature rotary valves at the bed ends, and E-seals to seal the beds to the valves. Several possible designs for introducing reactants into the beds also are disclosed. The multiple reformer beds are configured to provide for pressure equalization and ‘steam push’. The compact pressure swing reformer is suitable for use in fuel cell vehicle applications.
