The chlorine evolving reaction (CER) that subdues the oxygen evolving reaction (OER) during the electrolysis of seawater has long been an impediment to the attainment of producing hydrogen in volume without generating harmful byproducts containing chlorine. Using various often expensive catalysts to suppress CER and promote OER frequently requires complex chemical processes and is commonly limited to an operational electrical current density Jc of less than 1 A/cm2, which limits the production rate of hydrogen. In this paper, a new approach to suppress CER and increase the production rate of hydrogen. Two unconventional features in our approach are: the use of Jc (>10 A/cm2) much larger than those typically used (Jc 10 A/cm2) than conventionally used in seawater electrolysis (Jc |
