NOVELTY - Electrochemical cell (12) has anode chamber (14), intermediate chamber, cathode chamber (16), and unit for forming synthesis gas by reacting carbon dioxide and hydrogen. Chamber (14) has anode having source of water, in which water is decomposed into oxygen and hydrogen ion. Intermediate chamber has source (28) of sodium carbonate and hydrogen ion, in which sodium carbonate is decomposed into carbon dioxide, water and sodium ion. Cathode chamber has cathode having source of water and sodium ions, in which water is decomposed into sodium hydroxide and hydrogen.    USE - For producing synthesis gas containing carbon monoxide and hydrogen, used as liquid fuel for transportation.    ADVANTAGE - The electrochemical cell easily enables the manufacture of synthesis gas.    DETAILED DESCRIPTION - The electrochemical cell (12) has an anode chamber (14), an intermediate chamber separated from the anode chamber by a separator permitting transport of hydrogen ions, a cathode chamber (16) separated from intermediate chamber by a membrane permitting transport of sodium ions, and unit for facilitating reaction of carbon dioxide and hydrogen to form synthesis gas containing carbon monoxide and hydrogen. The anode chamber has electrochemically active anode having a source of water, in which water is decomposed into oxygen and hydrogen ion. The oxygen is then collected and removed from the anode chamber. The intermediate chamber has a source (28) of sodium carbonate and hydrogen ion, in which the sodium carbonate is decomposed into carbon dioxide, water and sodium ion. The carbon dioxide is collected and removed from the intermediate chamber. The cathode chamber comprises an electrochemically active cathode having a source of water and sodium ions, in which the water is decomposed into sodium hydroxide and hydrogen. Hydrogen and sodium hydroxide are collected and removed from the cathode chamber.    INDEPENDENT CLAIMS are included for the following:    (1) electrochemical process for producing synthesis gas; and    (2) electrochemical device.
