Abstract: The present disclosure relates to an ammonia synthesis apparatus, and more particularly, to an electrochemical ammonia synthesis apparatus using an aqueous solution or a molten liquid of an alkali metal as an electrolyte. According to one or more embodiments, when an aqueous solution or a molten liquid of an alkali metal is used as an electrolyte in an ammonia synthesis apparatus, compositions, sizes, and shapes of an electrode and an electrolyte may be easily controlled, and thus a yield of ammonia synthesis may improve.

Abstract: A unit cell includes an air inlet/outlet that is formed on a frame unit rather than being installed in a fuel electrode (anode) to simplify a sealing process, and accordingly, a continuous process using a tape casting technique may be performed. In addition, an electrolyte material that is in contact with an air electrode (cathode) in the frame unit is optimized to improve ion conductivity and a porosity of an upper layer material of the fuel electrode unit is optimized to increase fuel diffusion from a gas channel to an electrolyte layer. In addition, a sealing process performed inside the unit cell or between the unit cells of the stack is stabilized and strongly maintained, and thus a fuel cell using the unit cell and the stack disclosed herein may have excellent economic feasibility and high energy efficiency.

Abstract: A carbon dioxide conversion system is provided. The carbon dioxide conversion system includes: an ion transfer membrane that separates oxygen in the air; an oxy-fuel combustor that combusts using oxygen that is separated at the ion transfer membrane as an oxidizing agent; and a dry-reformer that converts carbon dioxide that is generated through an oxy-fuel combustion reaction of the oxy-fuel combustor and methane gas that is supplied from the outside to carbon monoxide and hydrogen by a dry-reforming reaction.

Abstract: The present invention provides: an electrode-supporting type of gas-separation membrane module for selectively effecting the passage of a gas via an electron exchange reaction due to a coupling-material layer and gas exchange via an ion-conducting separation layer; a tubular structure of same; a production method for the tubular structure; and a hydrocarbon-reforming method using the gas-separation membrane module. The present invention is advantageous in that outstanding chemical and mechanical durability can be ensured by using a fluorite-based ion-conducting membrane which is chemically stable in CO2 and H2O atmospheres in particular, at high temperature, and in that a pure gas can be produced inexpensively since the passage of gas occurs due to an internal circuit even without applying a voltage from the outside.
