Abstract
Provided are a hydrogen recycle system and a hydrogen recycle method, whereby hydrogen can be purified to high purity at high yield from a gas, said gas being exhausted from a nitride compound production device, and recycled. The hydrogen recycle systemcomprises an exhaust gas supply pathsupplying a gas exhausted from a nitride compound production device, a hydrogen recycle meansand a hydrogen supply path. The hydrogen recycle meansof the hydrogen recycle systemis characterized by comprising: a plasma reaction vesselthat defines at least a part of a discharge space; a hydrogen separation membranethat divides the discharge spacefrom a hydrogen flow pathcommunicated with the hydrogen supply path, defines at least a part of the discharge spaceby one surface thereof and also defines at least a part of the hydrogen flow pathby the other surface thereof; an electrodethat is disposed outside the discharge space; and an adsorbentthat is filled in the discharge spaceand adsorbs the supplied exhaust gas.
