Claim Text:
1. A multilayer module for hydrogen separation comprising: a pressure chamber having a mixed gas supply pipe which is disposed on a side thereof so as to be communicated therewith; and a separation unit which is installed in the pressure chamber, wherein the separation unit comprises: at least two laminated unit cells which are configured to separate hydrogen from a mixed gas; an upper plate which is placed on each of the laminated unit cells at an uppermost side; and a lower plate which is placed on each of the laminated unit cells at a lowermost side, at least one of the upper plate and the lower plate includes a hydrogen gas discharge pipe which are disposed thereon to discharge hydrogen separated from the separation unit, at least one of the upper plate and the lower plate includes a retentate gas discharge pipe which are disposed thereon to discharge a remaining retentate gas from which hydrogen has been separated by the separation unit, and each of the unit cells is communicated with an inner space of the pressure chamber, wherein each of the unit cells comprises: a cell body forming a main body of each of the unit cells; support protrusions formed on an upper recessed section of the cell body; a hydrogen separation plate which is disposed on the support protrusions to pass only hydrogen therethrough; a mixed gas communication hole, a retentate gas communication hole, and a hydrogen gas communication hole, which are formed in the cell body around the hydrogen separation plate, so as to be spaced apart from each other; a mixed gas input port which is formed in circumferential surfaces of the cell body thereof to be communicated with the mixed gas communication hole, and is exposed to the inner space of the pressure chamber to be communicated therewith; a mixed gas outlet hole which is communicated with the mixed gas communication hole through a mixed gas passage, and is formed in the bottom of the cell body to be exposed to a hydrogen separation plate of another unit cell adjacent thereto; a retentate gas input hole which is communicated with the retentate gas communication hole through the retentate gas passage, and is formed in the bottom of the cell body to be exposed to the hydrogen separation plate of the other unit cell adjacent thereto; a hydrogen gas inlet hole which is formed between the support protrusions and the lower portion of the hydrogen separation plate, and is communicated with the hydrogen gas communication hole through hydrogen gas passage, the hydrogen gas discharge pipe is communicated with the hydrogen gas communication hole, the retentate gas discharge pipe is communicated with the retentate gas communication hole, and a gap is formed between a lower surface of an upper unit cell and the hydrogen separation plate in the adjacent unit cell so as to communicate the mixed gas outlet hole with the retentate gas inlet hole therethrough.
