  • Aqueous based electrolyte slurry for MCFC and method of use
    Patent number: 6844102
    Abstract: The present invention provides an aqueous-based electrolyte slurry for molten carbonate fuel cells. The invention provides means to eliminate the potential for the preferential transport of potassium carbonate and subsequent irreversible alteration of the 62/38 molar ratio of the eutectic mixture of the lithium potassium carbonate electrolyte.
    Type: Grant
    Filed: February 27, 2002
    Date of Patent: January 18, 2005
    Assignee: GenCell Corporation
    Inventors: Jeffrey Peter Allen, David A. Schoonmaker
  • Aqueous electrode binder and electrodes and fuel cells including same
    Publication number: 20030170539
    Abstract: An aqueous binder for making an electrode is provided. The aqueous binder includes water, a polymeric alcohol, a non-polymeric alcohol, a water-soluble resin, a drying moderator, and optionally an anti-foaming agent. The aqueous binder typically includes mostly water such that minimal toxic substances are evolved when the aqueous binder is used to produce electrodes. Electrodes and fuel cells assembled using the aqueous binder are also described.
