A technique includes operating a fuel cell, which produces an effluent flow. The technique includes routing the effluent flow through an electrochemical pump to extract fuel from the effluent flow and providing the extracted fuel to the fuel cell.

High efficiency fuel cell system

A technique includes operating a fuel cell, which produces an effluent flow. The technique includes routing the effluent flow through an electrochemical pump to extract fuel from the effluent flow to produce a first feedback flow. The technique includes using the effluent flow to produce a second feedback flow separate from the first feedback flow and routing the second feedback flow through a venturi to the fuel cell.

Hydrogen pumps include a proton conducting medium, and a nonporous hydrogen permeable anode electrode and/or nonporous hydrogen permeable cathode electrode. For example, the electrodes may be a solid thin metallic film such as palladium or a palladium alloy such as a palladium-copper alloy that allow for hydrogen permeation but not impurities, and thus, purifying a supply containing hydrogen. The proton conducting medium may be a solid anhydrous proton conducting medium disposed between the anode electrode and the cathode electrode. The anode electrode and the cathode electrode may be directly sealed to at least one of the proton conducting medium, a first member for distributing the supply containing hydrogen to the anode electrode, a second member for collecting a supply of purified hydrogen, and a gasket disposed around the proton conducting medium.

Methods, devices, and infrastructure systems for separating, removing, compressing, and generating hydrogen

A technique includes introducing an electrical perturbation to a fuel cell system during operation of the fuel cell system. This electrical perturbation does not substantially disrupt the operation of the fuel cell system. In response to the perturbation, an electrical parameter of the fuel cell system is measured.
