Abstract: Alkaline membrane fuel cells designed with silver cathode catalysts include a catalyst layer comprising silver metal nano-particles and an anion-conducting ionomer. The silver nano-particles are mixed with a solution of the ionomer to form a catalyst ink that is applied to an alkaline membrane to form an ultra-thin cathode catalyst layer on the membrane surface.

Abstract: A device to produce electricity by a chemical reaction without the addition of liquid electrolyte comprises an anode electrode, a polymer membrane electrolyte fabricated to conduct hydroxyl (OH—) ions, the membrane being in physical contact with the anode electrode on a first side of the membrane, and a cathode electrode in physical contact with a second side of the membrane. The anode electrode and cathode electrode contain catalysts, and the catalysts are constructed substantially entirely from non-precious metal catalysts. Water may be transferred to the cathode side of the membrane from an external source of water.

Abstract: A thermal battery comprises a plurality of stacked cells, each cell consisting essentially of: a) a first anode comprising lithium or a lithium compound; b) a second anode comprising a second anode material; c) an oxidizing agent in contact with said second anode; and, d) a low temperature electrolyte placed between said first and said second anode. The second anode material is preferably selected such that it does not develop a substantial electric potential difference relative to the first anode.
Abstract: A thermal battery which comprises a number of stacked cells, each cell consisting essentially of an anode with a lithium compound, a lithium free pyrotechnic heat source pellet which includes a cathode precursor and an all lithium electrolyte layer separating between the anode and the pyrotechnic heat source pellet. Upon ignition of the heat source, an oxide of the cathode precursor is obtained which is lithiated by the lithium supplied by the all lithium electrolyte ion source.
