  • ELECTROCHEMICAL CELLS INCLUDING ELECTRODE STACKS FOR METAL-AIR BATTERIES
    Publication number: 20250273772
    Abstract: An electrochemical cell may include a vessel, a first module, a second module, and a gas diffusion electrode (GDE). The vessel has a thickness dimension. The first module includes a first anode sandwiched between two first oxygen evolution electrodes along the thickness dimension of the vessel. The second module includes a second anode sandwiched between two second oxygen evolution electrodes along the thickness dimension of the vessel. A gas diffusion electrode (GDE) is disposed between the first module and the second module in the vessel along the thickness dimension of the vessel.

  • GAS DIFFUSION ELECTRODES FOR METAL-AIR BATTERIES
    Publication number: 20250273697
    Abstract: The present disclosure is generally directed to a discharge cathode of a metal-air battery. A method of fabricating the discharge cathode includes forming a frame of electrically insulating material onto a terminal with a first end portion of the terminal exposed in a window defined by the frame and a second end portion of the terminal outside of the frame. The method includes positioning a gas diffusion electrode (GDE) on the frame with a busbar supported on the GDE and a bus tab extending from the busbar to the window. The method includes connecting the bus tab and the first end portion of the terminal to one another through the window. The method includes, with the bus tab and the terminal connected to one another, hermetically sealing the window.

  • PHOTOVOLTAIC MODULE MOUNTING SYSTEM AND METHOD
    Publication number: 20210297036
    Abstract: A photovoltaic (PV) module mounting system can have mounting clips that can be moved up and down a roof, and can allow the height of the mounting clips to be adjusted relative to the roof. At least a portion of the system can be made of a non-conductive material so that the system can be free of a grounding unit. The system can allow solar modules to be quickly installed, and can allow the solar modules to be removed quickly for repair or in the event of a fire.
