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.

Abstract: A fuel cell system is provided which includes a hydrocarbon fuel processor for generating hydrogen for use in a fuel cell. The system further includes a hydrogen buffer for storing a portion of the hydrogen generated by the fuel processor. The system further includes a staged hydrogen selective membrane providing pressurized hydrogen to the buffer. This stored hydrogen may then be used during start-up of the system in a number of ways, such as feed for the fuel cell, or when the fuel processor output is temporarily less than that required by the operating demand of the fuel cell.

Abstract: A method for producing a hydrogen containing gas for use in an internal combustion engine system is provided. The method includes cyclically operating at least two pressure swing reformer reactors such that one is reforming while another is regenerating, thereby producing a continuous stream of hydrogen containing gas. During engine operation exhaust gas is fed to the pressure swing reformer reactor that is undergoing regeneration, thereby supplying at least part of the heat for regeneration. Also, the hydrogen gas produced is used in at least one of (i) the engine; (ii) an engine exhaust treatment device; and (iii) a fuel cell.
