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.

Abstract: A fuel cell stack includes a first stack including a plurality of first fuel cells stacked on each other, and a second stack including a plurality of second fuel cells stacked on each other and disposed on one side of the first stack. Each of the first stack and the second stack includes a fuel inlet hole, through which fuel to be supplied to anodes of the respective first and second fuel cells is introduced, a fuel discharge hole, through which the fuel passing through the anodes is discharged, an air inlet hole, through which air to be supplied to cathodes of the respective first and second fuel cells is introduced, and an air discharge hole, through which the air passing through the cathodes is discharged. The fuel cell stack divided into the two stacks increases a charging ratio of hydrogen at the anodes of the respective stacks.

Abstract: A method of defogging an inner surface of a vehicle windshield glass. The method includes a first process of defogging by changing a heating, ventilation, and air-conditioning (HVAC) system from a heating mode to a cooling mode when fogging occurs on the inner surface of the vehicle windshield glass; once the inner surface of the vehicle windshield glass is changed to a defogging state by the first process, a second process of pre-defogging by turning off a compressor of the HVAC system for a predetermined period of time under a prescribed condition to prevent flash fogging; and after the second process, when the predetermined period of time elapses, a third process of turning on the compressor to return from the cooling mode to the heating mode.
