Abstract: An apparatus for separating hydrogen is provided to purify a large amount of hydrogen at a low energy cost from a mixed gas containing argon, hydrocarbons, methane, oxygen, nitrogen, carbon monoxide, hydrogen, and carbon dioxide. An apparatus(100) for separating hydrogen comprises: a temperature control unit(10) for controlling temperature of mixed gas containing hydrogen to a range of 200 to 800 °C; a hydrogen separation unit(20) including a plurality of hydrogen permeation membranes which are stacked in multistage within a housing for flowing in and out the mixed gas, and which are spaced apart from one another, and a hydrogen adsorption part and a hydrogen desorption part alternately formed between the hydrogen permeation membranes; and pressure control units(40) for controlling the pressure such that a pressure of the hydrogen adsorption part is higher than that of the hydrogen desorption part. The hydrogen permeation membrane is a metal membrane, a ceramic film, or a polymer film. The temperature control unit comprises a heater for heating the mixed gas. The hydrogen separation unit includes a hydrogen collector(50) for collecting desorbed hydrogen. The hydrogen separation unit includes an insulating member(30) for insulating the housing from the external air. Further, the insulating member comprises an insulating bed mounted on the housing and an insulating cover for insulating from external air.
