Abstract
Provided are electrochemical cells for hydrogen production and methods for hydrogen production. The electrochemical cell and methods use a mediator that may have a reversible redox potential lying outside the onset of the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). Also, provided are systems for generating hydrogen and water from oxygen and generating water from oxygen and hydrogen.
