  • Thermoelectrochemical process using copper oxide for producing hydrogen and oxygen from water
    Patent number: 4332650
    Abstract: A thermoelectrochemical process for production of hydrogen and oxygen from water providing a closed cycle reactant regenerative process wherein the primary energy input is thermal and a smaller electrical energy input is required for an electrolysis step. The process is a hybrid copper oxide-copper sulfate water splitting cycle using copper oxide reactant in the reactions producing both hydrogen and oxygen providing two phase reaction products in each step.
