摘要:
Fuel cell oxygen electrode and instant startup fuel cells employing such oxygen electrode. The oxygen electrode operates through the mechanism of redox couples which uniquely provide multiple degrees of freedom in selecting the operating voltages available for such fuel cells. Such oxygen electrodes provide the fuel cells in which they are used a “buffer” or “charge” of oxidizer available within the oxygen electrode at all times.

An active composition for an electrode of an electrochemical device. The active composition comprises a nickel hydroxide material, a graphite material, and a polymeric binder.
摘要:
A portable heating pack utilizing a supercorroding metallic alloy that produces heat and gaseous hydrogen upon contacting a corroding liquid. The portable heating pack provides for the consumption and/or storage of the gaseous hydrogen rather than venting the gaseous hydrogen from the portable heating pack.
摘要:
An active composition for an electrode of an electrochemical device. The active composition comprises an active electrode material, a carbon material, and a binder where the binder comprises an elastomeric polymer. Preferably, the active electrode material is nickel hydroxide, the carbon material is graphite and the elastomeric polymer is styrene-butadiene.

摘要:
A combination of photovoltaic devices and solid state batteries. The solid state battery comprising at least one negative electrode which may include a metal hydride active material, at least one positive electrode including an active material, and an anionic exchange membrane disposed between said negative electrode and said positive electrode. The anionic exchange membrane may be selected from materials allowing the flow of hydroxyl ions therethrough while simultaneously electrically separating the positive and negative electrodes. The anionic exchange membrane may be selected from a number of different materials based on different chemistries which allow the flow of hydroxyl ions therethrough. The anionic exchange membrane may be comprised of a polystyrene-divinylbenzene-polyvinylchloride polymeric material. The photovoltaic devices may be amorphous silicon solar cells. The photovoltaic devices may be triple junction, tandem amorphous silicon solar cells. The photovoltaic devices may be in the form of a roofing material. The photovoltaic devices may be deposited on thin film plastic material such as Kapton.
摘要:
Nickel hydroxide for use in an electrode of a rechargeable battery is prepared by controlled precipitation from a neutralized reaction mixture of a nickel salt and an alkali metal hydroxide. The controlled precipitation results in the formation of generally spherical particles having a high density. Pulsed or constant ultrasonic energy is applied to the mixture or to a portion thereof during the reaction to cause an alteration in the micro and macrostructures and the surface characteristics of the particles. These alterations result in enhanced performance characteristics of the resultant electrode.
