Title: Separator plates, ion pumps, and hydrogen fuel infrastructure systems and methods for generating hydrogen

Abstract: Anode and cathode separator plates are suitable for use in ion pumps for converting an input stream such as reformate into a pressurized and purified hydrogen-rich gas stream. The plates may include a single cathode outlet opening forming a portion of cathode output gas manifold, an anode inlet opening forming a portion of an inlet gas stream manifold and being sized larger than inlet cathode outlet opening, the distance of the anode inlet opening to an edge of the plate being less than the distance of the cathode outlet opening from an edge of the plate, and the size of the fluid flow channel of the anode separator plate being smaller than the size of the fluid flow channel of the cathode separator plate. Methods for forming the plates and infrastructure systems are also disclosed.
