Abstract
An electrochemical cell for the continuous acidification of alkaline water sources and recovery of carbon dioxide with simultaneous continuous hydrogen gas production having a center compartment, an electrolyte-free anode compartment having a mesh anode in direct contact with an ion permeable membrane, an endblock in direct contact with the anode where the endblock provides a gas escape route behind the anode, an electrolyte-free cathode compartment having a mesh cathode in direct contact with an ion permeable membrane, and an endblock in direct contact with the cathode where the endblock provides a gas escape route behind the cathode. Current applied to the electrochemical cell for generating hydrogen gas also lowers the pH of the alkaline water to produce carbon dioxide with no additional current or power. Also disclosed is the related method for continuously acidifying alkaline water sources and recovering carbon dioxide with continuous hydrogen gas production.
