  • SOLID OXIDE FUEL CELL HAVING A DENSE BARRIER LAYER
    Publication number: 20190157703
    Abstract: A solid oxide fuel cell with a dense barrier layer formed at or near the outer surface of the top and/or bottom electrode layers in a fuel cell stack. The dense barrier layer (DBL) acts as a seal to prevent gas in the electrode layer (either air in a cathode layer or fuel gas in an anode layer) from leaking out of the stack though the outer surface of the outermost electrode layers. The use of a DBL with porous outer electrode layers reduces the amount of gas escaping the stack and minimizes the chances for leak-induced problems ranging from decreases in performance to catastrophic stack failure.
    Type: Application

  • Method and diagnostic facility for checking high-pressure tank valves, high-pressure tank system and motor vehicle with a high-pressure tank system
    Patent number: 9976523
    Abstract: A method and diagnostic facility for checking a plurality of magnetic valves in a high-pressure tank system of a motor vehicle is described. A magnetic valve is activated for opening the magnetic valve. A pressure in a high-pressure tank system is measured while activating the magnetic valve. A valve is determined to be defective if during measuring the pressure a drop in pressure is found.
