Abstract: A display device is described comprising a first transparent electrode, a second electrode, and a pixel, wherein the pixel, in-between the first electrode and the second electrode, comprises a display molecule connected to a first surface, the display molecule comprises an electron donor, a conjugated bridge and an electron acceptor.

Abstract: An air-cooled, hydrogen-air solid polymer electrolyte (SPE) fuel cell with a membrane electrode assembly operatively associated with a fluid flow plate having at least one plate cooling channel extending through the plate and at least one air distribution hole extending from a surface of the cathode flow field into the plate cooling channel.

Abstract: A H.sub.2 /F.sub.2 power generating system is disclosed. The system is particularly useful in producing power in military and space vehicle applications because of its high energy density and long shelf life.

Abstract: A continuous process for the removal of hydrogen sulfide from a gas stream using a membrane comprising a metal oxide deposited on a porous support is disclosed.

Abstract: The present invention includes a primary battery of the remotely activated type which may include one or more zinc electrodes and which is filled with a liquid electrolyte only when the battery is to be activated. A novel feature of the invention is the use of an acid or mixture of acids in aqueous solution as the electrolyte. Hydrochloric acid, phosphoric acid and sulfuric acid are preferred, although other acid can also be used in various concentrations as the electrolyte. The voltage of the battery is unexpectedly higher and the battery has a faster activation time at low temperatures than if an alkaline electrolyte were used. A superior high voltage short duration battery is thus obtained.

Abstract: The present invention is directed to a zinc electrode of improved type for alkaline batteries of the deferred action or reserve type, which batteries include a silver oxide electrode and a separator. The zinc electrode is provided with a current collector having a foil or grid of aluminum or aluminum alloy therearound adjacent the surface of that electrode. The foil or grid may have an increased surface area provided by a profile which has been etched or otherwise disposed therein. The current collector can include a copper core. The foil or grid can be applied to both sides of the core and a sheet of zinc can be applied to each sheet of the foil or grid. The resulting zinc electrode has increased resistance to passivation which normally occurs at low temperatures and when zinc electrodes are discharged at high current densities. An improvement in the efficiency of the zinc electrode at high current density as well as low temperatures is provided in accordance with the present invention.
