  • Direct ammonia alkaline membrane fuel cell and method of operating same
    Patent number: 11309568
    Abstract: Disclosed is a method of operating an Alkaline Membrane Fuel Cell (AMFC) with direct ammonia feeding. The method may include providing AMFC comprising an anode inlet for receiving ammonia and a cathode inlet for receiving oxygen containing gas; operating the AMFC at an operation temperature of above 80° C.; providing the oxygen containing gas; to a cathode of the AMFC at a pressure above the equilibrium vapor pressure of water at the operation temperature; maintaining the pressure during the operation of the AMFC as to maintain water in substantially liquid phase near the cathode; and providing the ammonia to an anode of the AMFC.
    Type: Grant
    Filed: July 28, 2019
    Date of Patent: April 19, 2022
    Assignee: HYDROLITE LTD
    Inventors: Ben Achrai, Gal Tamir, Miles Page, Shimshon Gottesfeld, Ervin Tal-Gutelmacher
  • Multi-metallic electro-catalyst for alkaline exchange membrane fuel cells and method of making same
    Patent number: 11228050
    Abstract: Some aspects of the invention may be directed to a catalyst layer for anodes of Alkaline Exchange Membrane Fuel Cells (AEMFC). Such catalyst layer may include catalyst nanoparticles and an ionomer. Each catalyst nanoparticle may include one or more nanoparticles of catalytically active metal supported on at least one nanoparticle of crystalline RuO2. The diameter of the at least one nanoparticle of the crystalline RuO2 may be about order of magnitude larger than the diameter of the one or more nanoparticles of catalytically active metal.
