US 2026/0159967 A1 · ACIDIFICATION OF SEAWATER IN AN ELECTROLYTIC - CATION EXCHANGE MODULE (E-CEM) DEVICE

Abstract

An apparatus for generation of at least one of carbon dioxide or hydrogen from saline water is disclosed. The apparatus includes an anodic compartment, an anode on a first side of the anodic compartment, a cathodic compartment, a cathode on a first side of the cathodic compartment, a first cation permeable fluidic separator on a second side of the anodic compartment, a second cation permeable fluidic separator on a second side of the cathodic compartment, a center compartment between the first and second cation permeable fluidic separators, and a mixing chamber including an inlet fluidly connectable to or in fluid communication with the outlet of the anodic compartment and an outlet, the center compartment having one of an outlet fluidly connectable to or in fluid communication with the inlet of the mixing chamber or an inlet fluidly connectable to or in fluid communication with the outlet of the mixing chamber.
