Abstract
A system and method for generating hydrogen gas from an aqueous solution are disclosed herein. The system comprises a compartment with a working electrode for reducing water in response to an applied voltage to generate hydrogen and a redox-active electrode capable of reversibly undergoing oxidation and reduction. The system may further comprise a second compartment with a working electrode for generating oxygen and redox-active electrode electrically connectable to the redox-active electrode in the first compartment. The method comprises applying a voltage between a working electrode and a redox-active electrode of a system described herein and/or between comprising a working electrode of one compartment and a working electrode of a second compartment of a system described herein.
