▎ 摘  要

NOVELTY - Graphene synthesizing device comprises a gas supplying unit (10) for supplying hydrocarbon-based gas, a graphene synthesizing chamber (20) for synthesizing graphene film by using hydrocarbon-based gas supplied from the gas supplying unit and discharging the exhaust gas containing hydrogen gas generated during the synthesis process of the graphene film, and a hydrogen gas collecting unit (30) for collecting hydrogen gas contained in the exhaust gas discharged from the graphene synthesizing chamber. USE - Used as graphene synthesizing device. ADVANTAGE - The device produces hydrogen gas of high purity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for driving the graphene synthesizing device, comprising (a) heating the internal space of the graphene synthesizing chamber to a first temperature, and injecting hydrocarbon-based gas into the internal space, (b) dissociating carbon atom and hydrogen atom of hydrocarbon-based gas, and discharging the exhaust gas contained in hydrogen gas of the internal space to the outside, (c) obtaining the graphene film by cooling the internal space at a temperature lower than the first temperature, and (d) filtering hydrogen gas from the exhaust gas, and storing hydrogen gas. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene synthesizing device.
