DETAILED DESCRIPTION - An electrochemical device comprises 1st electrode (101) and 2nd electrode (102) separated by a distance and aligned in parallel and 1st conduit (111) and 2nd conduit (112) connected in perpendicular and electrically coupled to 1st electrode and 2nd electrode, respectively. Configuration of 1st and 2nd electrodes and 1st and 2nd conduits form a unit cell structure. A fluid containing electrolyte and non-oxygenated substance is dispersed between 1st and 2nd electrodes, and electric potential applied across 1st and 2nd conduits induces oppositely charged sides of 1st and 2nd electrodes to form a cathode side and an anode side of corresponding electrode and generates an electric field converting the electrolyte in an oxidative process that releases electrons captured at the anode and reducing the non-oxygenated substance to gain electrons at the cathode, producing a chemical product and extracting energy from the electrolyte. An INDEPENDENT CLAIM is included for production of fuel substance and electrical energy which involves supplying water as electrolyte to greater than or equal to 2 interior cavities of electrochemical device structured to include 1st and 2nd electrodes, 1st and 2nd conduits, interior cavities, housing structure formed of insulative material coupled to 1st and 2nd conduits and encloses 1st and 2nd electrodes, and greater than or equal to 2 interior boundary walls coupled to housing structure and arranged in parallel between 1st and 2nd electrodes to form greater than or equal to 2 interior cavities, releasing reactant substance through greater than or equal to 1 layers of synthetic crystalline material of 1st electrode into 1st interior cavity of greater than or equal to 2 interior cavities, applying electric potential at 1st and 2nd conduits to produce intermediary chemical products, and selectively transferring greater than or equal to 1 of the produced intermediary chemical products to 2nd interior cavity in which generated electric field causes chemical conversion of selectively transferred reactant substance and electrolyte in 2nd interior cavity catalyzed by synthetic crystalline material of 2nd electrode to produce chemical fuel, and chemical conversions release electrical charge carriers extracted as electrical energy at the electrodes.
