Latest Patents

One of Said Al Hallaj's latest patents is titled "Method and apparatus for electrostatic spray deposition for a solid oxide fuel cell." This invention describes a method for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate made of nickel-YSZ cermet. By reducing the thickness of the electrolyte, the internal IR drop of the cell is minimized, allowing the intermediate temperature SOFC (ITSOFC) to operate efficiently at temperatures between 600–800°C. The design includes a collar positioned at a distance from the discharge end of a spray nozzle, which enhances the spray pattern of the precursor material, resulting in a very thin electrolyte layer.

Another significant patent is "Thermal management of battery systems." This invention outlines a method for operating a power supply system that involves discharging a battery module to produce power and heat. The method includes absorbing a portion of the heat in a phase change material that is in thermal contact with the discharging cell element. After discharge, the heat is released from the phase change material to reheat the cell element, allowing it to discharge at elevated temperatures.
