Patents by Inventor Thomas Pietri

Thomas Pietri 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).

  • Substrate made of porous metal or metal alloy, preparation method thereof, and HTE or SOFC cells with a metal support comprising this substrate
    Patent number: 9005846
    Abstract: A partly oxidized substrate is disclosed. According to one aspect, the substrate is formed by subjecting a substrate made of a porous metal or metal alloy including particles of at least one metal or metal alloy bound by sintering. The substrate includes a first main surface and a second main surface. The porosity of the substrate gradually changes from the first main surface to the second main surface. The substrate is partially oxidized by an oxidizing gas such as oxygen and/or air. A method for preparing the substrate and high temperature electrolyzer (THE) cell including the substrate are also disclosed.

  • SUBSTRATE MADE OF POROUS METAL OR METAL ALLOY, PREPARATION METHOD THEREOF, AND HTE OR SOFC CELLS WITH A METAL SUPPORT COMPRISING THIS SUBSTRATE
    Publication number: 20110287340
    Abstract: A partly oxidized substrate, obtained by subjecting a substrate made of a porous metal or metal alloy comprising particles of at least one metal or metal alloy bound by sintering, said substrate comprising a first main surface and a second main surface, and said substrate having a porosity gradient from the first main surface to as far as the second main surface; to partial oxidation by an oxidizing gas such as oxygen and/or air. Method for preparing said substrate and high temperature electrolyzer cell (<<HTE>>) comprising said substrate.
