    摘要: The invention relates to a process for gas phase electrochemical oxidation of H2S to sulfur and water or steam using an electrolysis cell having an anode chamber on one side of a solid proton conducting membrane and a cathode chamber on the other side of the membrane. The process comprises the steps of passing H2S-containing gas through the anode chamber to contact a catalytic anode, where it reacts to produce elemental sulfur, protons and electrons. The protons pass through the membrane from the anode chamber to the cathode chamber. An oxygen-containing gas is passed through the cathode chamber to contact the catalytic cathode, where it reacts with protons and electrons to produce water or steam. During the process, both the anode chamber and cathode chamber are maintained at a temperature of at least 120° C. and an elevated pressure sufficient to keep the membrane moist. Sulfur is obtained in liquid or vapor form and is removed from the anode chamber while water or steam is removed from the cathode chamber. An electric current can be withdrawn from the anode and cathode. The cell can also be operated in the electrolysis mode to produce sulfur and hydrogen.

    摘要: A method of forming hydrogen gas comprises the steps of providing a reactor and providing a hydrogen-generating composition to the reactor. The hydrogen-generating composition consists essentially of a borohydride component and a glycerol component. The borohydride, e.g. sodium borohydride, and glycerol components are present in a generally three (3) to four (4) stoichiometric ratio, prior to reaction. The borohydride component has hydrogen atoms and the glycerol component has hydroxyl groups with hydrogen atoms. The method further comprises the step of reacting the borohydride component with the glycerol component thereby converting substantially all of the hydrogen atoms present in the borohydride component and substantially all of the hydrogen atoms present in the hydroxyl groups of the glycerol component to form the hydrogen gas. The reaction between the borohydride component and the glycerol component is an alcoholysis reaction. Reactors and reaction systems employing the method of the present invention are also described.

    摘要: An integrated PEM fuel cell includes bipolar plate assemblies that utilize fiber groups that extend from the surfaces of gas impermeable plates to terminate in uncoated tips facing adjacent tips to form anodes and cathodes of an MEA assembly. The catalyst support and catalyst can be applied to the tips as beads or thin layers and joined with a membrane. The assembly can use a unified seal and include collector plates at the ends of the stacks, using similar fiber construction.
