Patents Assigned to Proton Energy Systems
  • Electrochemical cell frame
    Patent number: 6099716
    Abstract: A cell frame is for use in an electrochemical cell wherein the cell frame includes fluid communicating inserts for providing process water to the electrochemical cell and to transport waste water and product from the cell. The cell frame comprises inserts positioned about the periphery of the frame to facilitate a uniform fluid field and membrane hydration. The cell frame further comprises a protective plate comprising sealing features and lip extensions to prevent fluid leakage and membrane damage.

  • Hydrogen electrochemical system environment
    Patent number: 5980726
    Abstract: The present invention relates to a unique, compact hydrogen electrochemical system which eliminates the need for explosion-proof equipment. This system merely separates the electrical equipment from the hydrogen source with a wall, but employs a positive pressure, of about 0.1 inches water column, air purge throughout the system to prevent the introduction of hydrogen gas to the electrical equipment and to recover and use waste heat.
