Latest Patents
One of Jaffrey's latest patents is a fuel cell gas separator. This invention comprises a layer of copper or a copper-based alloy that features an oxidation-resistant material on the cathode side. A protective layer may also be provided on the anode side of the copper or copper-based alloy layer. The copper-based alloy may be aluminum bronze, which allows the oxidation-resistant layer to form automatically. Alternatively, the copper or copper-based alloy layer can be wrapped in a foil of heat-resistant steel, among other possibilities.
Another notable patent is for electrically conductive ceramics. This invention involves a metal oxide ceramic material, such as alumina or chromia, which has been rendered electrically conductive by incorporating silver into the material. The ceramic material can be applied as a layer on a substrate, such as a bipolar plate for a fuel cell assembly. The electrical conductivity is achieved by heating the ceramic material and a silver-containing material together at temperatures of at least 750°C, allowing silver to migrate and create conductive pathways through the ceramic.
