Abstract: The present invention relates to a carbon nanotube manufacturing apparatus, and a carbon nanotube manufacturing apparatus according to an embodiment of the present invention comprises: a reactor body formed in a cylindrical shape and having an accommodation portion which is a space in which a reaction occurs; and a distribution plate which is positioned below the accommodation portion of the reactor body and distributes a reaction gas supplied to the accommodation portion. The reactor body comprises: a lower reactor; an upper reactor having a diameter greater than that of the lower reactor; and an expansion portion which connects the upper reactor to the lower reactor and has a gradually expanding diameter. Related methods are also described.

Abstract: The present disclosure relates to a technique for manufacturing a humidifying membrane including a hydrophobic thin film-coating layer having a nano-sized crack morphology pattern on the surface of an aromatic hydrocarbon-based polymer ion exchange membrane and applying the membrane to a reverse electrodialysis process. The humidifying membrane including a hydrophobic thin film-coating layer having a nano-sized crack morphology pattern on the surface of an aromatic hydrocarbon-based polymer ion exchange membrane, manufactured according to the present disclosure, embodies a low bulk resistance of the ion exchange membrane and significantly improves ion selectivity, thereby overcoming the trade-off relationship between membrane resistance and ion selectivity, and thus may be commercially available as an anion and cation exchange membrane of a reverse electrodialysis device.

Abstract: The disclosed spinning nozzle member for manufacturing a cylindrical cartridge carbon filter comprises a nozzle body, a synthetic resin spinning part, a flowing air providing part, and a carbon spinning part, thereby enabling the cylindrical cartridge carbon filter to be continuously produced since a separate operation for filling a space between a core and an outer cover with carbon after the core and the outer cover are separately formed is not required.

Abstract: Disclosed are a polymer ion exchange membrane having a self-hydration capability at a high temperature under low humidity, a method of preparing the polymer ion exchange membrane, and a polymer electrolyte fuel cell system including the polymer ion exchange membrane. The polymer electrolyte membrane includes a hydrocarbon-based proton conductive polymercoating layer, and has a nano-crack on the hydrophobic surface and thus may secure ion conductivity and self-hydration capability under low humidity and remarkably improve electrochemical performance of an electrolyte.
