A recently granted patent (Publication Number: US11885032B2) discloses a method for operating an electrochemical device involving a nonlinear chemical reaction in a non-oscillatory regime. The method includes intentionally imposing an additive extrinsic stochastic disturbance to the potential difference between the working electrode and the counter electrode of the device. This disturbance, externally controlled and distinct from inherent noise, is applied in addition to the voltage, with a mean value within a specified range relative to the onset potential of the electrochemical reaction. The method is specifically designed for systems exhibiting nonlinear dynamics and away from equilibrium, ensuring the disturbance is only applicable to the non-oscillatory regime.
Furthermore, the patent details variations in the method based on the role of the working electrode, whether acting as an anode or cathode, and the presence of photoactive materials. The extrinsic stochastic disturbance can follow different noise patterns such as White, Colored, or Gaussian, with specific intervals of application duration ranging from 0.001 seconds to 5 seconds. The method provides a comprehensive framework for optimizing electrochemical device operation by strategically introducing controlled disturbances to enhance the efficiency and effectiveness of the nonlinear chemical reactions occurring within the system. The patent's detailed claims offer valuable insights into the innovative approach of leveraging extrinsic stochastic disturbances to manipulate electrochemical processes, opening up new possibilities for advancements in this field.
