Abstract: The present invention relates to a manufacturing apparatus and method for customizing a H2/CO synthetic gas in a desired ratio by producing a synthetic gas in which H2 and CO are mixed through hydrolysis of both carbon dioxide and a nitrogen compound with low power. In a low-power electrochemical apparatus for producing a synthetic gas according to the present invention, by performing the reduction of the carbon dioxide at the cathode and the oxidation of the nitrogen compound at the anode at the same time, carbon dioxide conversion efficiency may be improved 30% or more compared to the conventional carbon dioxide conversion system, and a synthetic gas with a desired H2/CO ratio may be produced by controlling the H2/CO ratio of the produced synthetic gas, and by reducing a driving voltage, the corrosion problem of electrode materials may be inhibited and the durability of electrodes may be increased.
