  • Stabilized carbonate fuel cell cathode
    Patent number: 4992342
    Abstract: Migration and/or dissolution of Ni from the cathode of a molten carbonate fuel cell is retarded by the incorporation of a constituent adapted to effect such retardation.
    Type: Grant
    Filed: April 19, 1985
    Date of Patent: February 12, 1991
    Assignee: Energy Research Corporation
    Inventors: Prabhakar Singh, Randolph M. Bernard, Lawrence M. Paetsch, Ronald D. Chamberlin
  • Prevention of corrosion of electrolyte cell components
    Patent number: 4512857
    Abstract: Disclosed is a method of operating an electrolytic cell having an active, catalytic cathode and an iron structure in contact with an alkaline electrolyte. The dissolution of iron into the electrolyte is reduced by a sacrificial anode in proximity to, and preferably in contact with, the iron structure.
    Type: Grant
    Filed: November 24, 1982
    Date of Patent: April 23, 1985
    Assignee: PPG Industries, Inc.
    Inventor: Ronald D. Chamberlin
  • Method of operating an electrolytic cell
    Patent number: 4379035
    Abstract: Discloses a method of operating a chlor-alkali cell having a low hydrogen overvoltage cathode and exposed high hydrogen overvoltage metal structure within the cathode compartment, where a composition of sodium nitrite and sodium benzoate is added to the catholyte to avoid corrosion of the exposed, high hydrogen overvoltage metal.
    Type: Grant
    Filed: May 10, 1982

  • Fixed bed oxygen depolarized cathode chlor-alkali cell
    Patent number: 4313813
    Abstract: Disclosed is a method of electrolyzing alkali metal chloride brine between an anode and a cathode, with oxidant feed to the cathode, where the cathode is a bed of porous particles having HO.sub.2.sup.- disproportionation catalyst. Also disclosed is an electrolytic cell for carrying out the disclosed process.
    Type: Grant
    Filed: June 26, 1980
    Date of Patent: February 2, 1982
    Assignee: PPG Industries, Inc.
    Inventors: Harlan B. Johnson, Ronald D. Chamberlin
  • Method of preparing electrocatalyst for an oxygen depolarized cathode electrolytic cell
    Patent number: 4292197
    Abstract: Disclosed is a method of preparing a cathodic electrocatalyst where the cathode is a bed of porous particles having HO.sub.2.sup.- disproportionation catalyst dispersed on the surfaces and pores thereof.
    Type: Grant

  • Method of electrolysis
    Patent number: 3990957
    Abstract: Disclosed is a method of electrolyzing an aqueous alkali metal chloride, which method comprises passing an electrolytic current from an anode of an electrolytic cell through an alkali metal chloride electrolyte to a cathode of the cell, evolving chlorine at the anode and hydrogen at the cathode. The method is characterized by the use of a cathode having a layer of an oxy-compound of a platinum group metal and an alkaline earth metal on an electroconductive cathode substrate.
