Nieves Lapeña-rey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • CHROMIUM-FREE CONVERSION COATING
    Publication number: 20100009083
    Abstract: A chromium-free conversion coating is prepared by the addition of inorganic salts to dispersions of conducting polymers which are then exposed to alloys of aluminum or other metals. Advantageously, the performance of the coating is comparable to that of known Cr (chromium)-based methods for a number of aluminum alloys having particular significance in the manufacture of aircraft.

  • Fuel cell module
    Patent number: 7473482
    Abstract: A solid oxide fuel cell module (30) comprises a plurality of fuel cells (36). Each fuel cell (36) comprises a first electrode (40), an electrolyte (42) and a second electrode (44). A plurality of interconnectors (38) are arranged to electrically connect the fuel cells (36) in electrical series. Each interconnector (38) electrically connects a first electrode (40) of one fuel cell (36) to a second electrode (44) of an adjacent fuel cell (36). The first electrode (40) comprises a first layer (40A) on the electrolyte (42 to optimize the electrochemical activity at the electrolyte (42) and a second layer (40B) on the first layer (40A) to provide electronic conduction perpendicular to the layers (40, 42, 44) of the fuel cell (36). The second layer (40B) is arranged such that electronic conduction perpendicular to the layers (40, 42, 44)) of the fuel cell (36) is different at different positions in the second layer (40B).
