  • METALLIC BIPOLAR PLATE FOR FUEL CELL
    Publication number: 20090280386
    Abstract: Proposed are a bipolar plate for a fuel cell and a method for the manufacture thereof. A simple, cost-effective manufacture is achieved with particularly good characteristics (high electrical conductance, high resistance to corrosion) by coating metallic plate material with Ti3SiC2 and subsequently forming it.

  • Rebalance cell for a Cr/Fe redox storage system
    Patent number: 5258241
    Abstract: The invention provides a rebalance cell for a Cr/Fe redox storage system. The rebalance cell has a catalyst for the reduction of Fe.sup.3+ ions by means of hydrogen. The catalyst separates a gas chamber of the rebalance cell (holding hydrogen) and a liquid chamber of the rebalance cell (holding Fe.sup.3+ electrolyte). The catalyst is in the form of an activated charcoal made hydrophobic and coated with a platinum metal, gold or silver. The catalyst can also be in the form of tungsten carbide made hydrophobic.

  • Redox battery
    Patent number: 4882241
    Abstract: The combination of gold, thallium, lead and bismuth is used as a catalyst in a battery comprised of at least one "redox" cell to accelerate the oxidation of chromous ions to chromic ions and the reduction of chromic ions to chromous ions. The gold, thallium, lead and bismuth catalyst is coated on an electronically conductive, inert electrode which is in the anode fluid of the "redox" cell.
