  • Method to actively control cell pressure drop during operation
    Patent number: 10186723
    Abstract: A method for controlling a pressure drop across the anode side or the cathode side of a fuel cell stack by controlling the intrusion of a cell separator into the flow channels in a feeder region of the stack so as to create a larger pressure volume on a pressure bias side of the stack. The method controls the flow rates of one or both of the cathode and anode reactant gases so as to cause the cell separators in an inlet feeder region and/or an outlet feeder region to move relative to the anode side and the cathode side so as to change a flow volume in the inlet feeder region and/or the outlet feeder region to control the pressure drop.
    Type: Grant

  • MEMBRANE ELECTRODE ASSEMBLY FABRICATION
    Publication number: 20110162784
    Abstract: A method for fabricating MEAs employing such gas diffusion layers and or gas diffusion electrodes that address the problems attendant to conventional methods. Due to the mechanically unstable nature of the electrolyte membrane material, it is advantageous to attach or bond the electrolyte membrane material to a supportive substrate before being sized for incorporation into a fuel cell. The GDL or GDE is used as the supportive substrate for the electrolyte membrane material.
