    摘要： 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.

    摘要： A solid oxide fuel cell power generation system's entire output is made up of three streams: water, sequestered carbon dioxide provided into a storage tank, and carbon dioxide depleted air. Thus, the system generates electricity from a hydrocarbon fuel, while outputting substantially no pollutants into the atmosphere and cleaning the air by removing carbon dioxide from the air exhaust stream. Thus, the system outputs cleaner air than it takes in without releasing pollutants into the atmosphere, while generating electricity from a readily available hydrocarbon fuel, such as natural gas.

    摘要翻译： 固体氧化物燃料电池发电系统的全部输出由三个流组成：水，隔离二氧化碳提供到储罐和二氧化碳贫化空气中。 因此，该系统从碳氢化合物燃料产生电力，同时基本上没有污染物输送到大气中并通过从排气流中除去二氧化碳来清洁空气。 因此，与天然气等容易获得的碳氢燃料发电相比，系统输出的清洁空气不会将污染物排放到大气中。

    摘要： A method of operating a fuel cell system includes providing a fuel inlet stream into a fuel cell stack, operating the fuel cell stack to generate electricity and a hydrogen containing fuel exhaust stream, separating at least a portion of hydrogen contained in the fuel exhaust stream using a cascaded electrochemical hydrogen pump, such as a high temperature, low hydration ion exchange membrane cell stack having at least two membrane cells arranged in process fluid flow series, and providing the hydrogen separated from the fuel exhaust stream into the fuel inlet stream.

    摘要： The invention provides a fuel cell system, including a fuel cell having an anode chamber and a cathode chamber, wherein the anode chamber is in fluid communication with a hydrogen reservoir, and wherein the cathode chamber has an inlet and an outlet. The cathode chamber comprises non-intersecting flow channels, and the non-intersecting flow channels provide fluid communication between the cathode inlet and outlet. The fuel cell has a first connection to an electrical load, wherein the first connection comprises a first diode adapted to prevent current flow to the fuel cell. A blower is in fluid communication with the cathode inlet. The blower has an electronic connection to a controller, and the blower is adapted to vary a flow of oxygen through the cathode chamber according to a control signal received from the controller. The system includes a battery having a second connection to the electrical load, the second connection being in parallel with the first connection of the fuel cell to the load, and the second connection comprising a second diode adapted to prevent current flow to the battery. The controller maintains the flow of oxygen such that an output power capacity of the fuel cell is limited by the amount of oxygen flowed through the fuel cell.

    摘要： Due to the limited structural integrity of the ion exchange membrane, operation at pressure gradients exceeding about 200 psi can cause electrolyzer failure due to the ion exchange membrane being physically forced into the holes of the screen set forming the chamber on the lower pressure side of the ion exchange membrane. Utilizing a porous sheet between the anode electrode and the screen set provides additional structural integrity to the ion exchange membrane and allows simultaneous dual-directional flow of water to the anode electrode while oxygen flows from the anode electrode, thereby allowing high pressure gradient operation.
