Abstract

The present invention relates to a hydrogen production module by an integrated reaction/separation process, and a hydrogen production reactor using the same, and more specifically, provides a hydrogen production apparatus which laminates a plurality of layered unit cells, is mounted in a pressure-resistant chamber, and can be operated at a high pressure, wherein the unit cell comprises a first modified catalyst, and a second modified catalyst opposite to a hydrogen separator. The hydrogen production module can produce hydrogen using a hydrocarbon, carbon monoxide and an alcohol as sources. Particularly, all the modified catalysts are formed into a porous metal plate form, thereby maximizing the heat transfer effect necessary for reaction. While a reaction and separation of hydrogen simultaneously occur, separated reactants permeate the first modified catalyst so as to come in contact with the same, and then pass through the gap between the hydrogen separator and the second modified catalyst opposite to each other. Therefore, it is possible to obtain a high efficiency over the equilibrium conversion rate of reaction temperature, and high purity hydrogen can be obtained.
