New Delhi, Feb. 19 -- USA based Nanodynamics Inc filed patent application for anode-supported solid oxide fuel cells using a cermet electrolyte. The inventors are Caine Finnerty and David Coimbra.
Nanodynamics Inc filed the patent application on May 30, 2006. The patent application number is 3091/DELNP/2006 A. The international classification number is H01M 8/00.According to the Controller General of Patents, Designs & Trade Marks, "Novel solid oxide fuel cell (SOFC) article and method of manufacture with improved properties at lower costs. The structural features and methods involve fabricating an anode (i.e., fuel electrode); applying a cermet electrolyte, which includes a mixture of ceramic and electrochemically active substances, and applying a cathodic layer. The cermet electrolyte containing a small amount of transition metal reduces the thermal expansion mismatch with the anode, and allows for a graded structure of the electrochemically active substances across the anode/electrolyte structure. Under operating conditions, a dense electrolyte and metal oxide sub-layer exist on the oxidized side (cathode side); while the other side of the electrolyte (reducing side) is made of a porous sub-layer containing transition metal. The tailoring of the amounts of metal present in the anode and the cermet electrolyte allows for greater power output and enhanced electrochemical performance, while maintaining the structural integrity and reliability of the SOFC."NanoDynamics, Inc. develops and markets products, advanced materials, and process technologies that provide clean technology solutions for the energy, environmental, and infrastructure markets. Its products include Revolution solid oxide fuel cells for use in portable, residential, and distributed power generation; Cell-Pore water filters; a range of advanced materials, including nano-sized metal and ceramic powders, carbon nano-tubes, nano-structured steel, and nano-cement; and process intensification technologies that reduce energy consumption, decrease use of hazardous chemicals and solvents, improve throughput rates and lower capital investment requirements. The company has collaborative agreement with Kodak, Tata Chemicals, and Otsuka Chemical. NanoDynamics, Inc. was founded in 2002 and is based in Buffalo, New York. On July 27, 2009, NanoDynamics Inc filed a voluntary petition for liquidation under Chapter 7 in the US Bankruptcy Court for the Western District of New York.
