  • SYSTEMS AND METHODS FOR PRODUCING HYDROGEN GAS
    Publication number: 20250171920
    Abstract: An electrolyzer system comprises one or more electrolyzer cells each comprising a first half cell with a first electrode and a second half cell with a second electrode and a controller to control a current applied through the one or more electrolyzer cells, wherein the controller is configured to dynamically set the current density within a current density range of from about 150 mA/cm2 to about 3000 mA/cm2, and wherein the controller is configured to set the current density to a first value when a first condition is met and to a second value when a second condition is met.

  • Systems and methods for producing hydrogen gas
    Patent number: 12037694
    Abstract: A method for carrying out electrolysis comprises dynamically changing a current density associated with an operation of an electrolyzer within a range of values of about 0.15 A/cm2 and 3.0 A/cm2, wherein the changing of the current density associated with the operation of the electrolyzer is in response to a change in demand for electricity within a region where the electrolyzer is located, and wherein the changing of the current density comprises lowering the current density within the range of values of about 0.15 A/cm2 and 3.0 A/cm2 when the demand for electricity increases within the region where the electrolyzer is located and raising the current density within the range of values of about 0.15 A/cm2 and 3.0 A/cm2 when the demand for electricity decreases within the region where the electrolyzer is located.
