Anatoly Demin 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).

  • Modified planar cell (MPC) and stack based on MPC
    Patent number: 8409763
    Abstract: A single cell for a solid oxide fuel cell having wave-like architecture and a stack composed of such single cells is described. The cell design provides high durability. The stack design provides uniform distribution of reagents along the surface of the electrodes and between the individual cells. In addition the stack design is non material intensive.
    Type: Grant
    Filed: August 8, 2007
    Date of Patent: April 2, 2013
    Assignee: Solid Cell, Inc.
    Inventor: Anatoly Demin
  • Interconnect material for solid oxide fuel cell and process for the preparation thereof
    Patent number: 8226858
    Abstract: An interconnect composite material having a coefficient of thermal expansion close to that of zirconia electrolyte, high electrical conductivity, high stability in both oxidizing and reducing atmosphere at temperatures from 600 to 900° C. and having the following general composition (1?z)[xNi+(1?x?y)TiO2+yNb2O5]+zCuO where x, y and z are corresponding parties of weight. An interconnect plate of this material is manufactured by sintering an intermediate TiO2—Nb2O5 composition, grinding it to a powder, combining the powder with NiO, CuO and an organic binder, tape casting the mixture, stacking the fabricated film into multiple layers, repeated rolling of the multiple layers into sheets and two-step sintering of the sheets in an air atmosphere at the first step and in a hydrogen atmosphere at the final step.

    Abstract: An interconnect composite material having a coefficient of thermal expansion close to that of zirconia electrolyte, high electrical conductivity, high stability in both oxidizing and reducing atmosphere at temperatures from 600 to 900° C. and having the following general composition (1-z)[xNi+(1-x-y)TiO2+yNb2O5]+zCuO where x, y and z are corresponding parties of weight. An interconnect plate of this material is manufactured by sintering an intermediate TiO2—Nb2O5 composition, grinding it to a powder, combining the powder with NiO, CuO and an organic binder, tape casting the mixture, stacking the fabricated film into multiple layers, repeated rolling of the multiple layers into sheets and two-step sintering of the sheets in an air atmosphere at the first step and in a hydrogen atmosphere at the final step.
