摘要： A heat treatment apparatus for a fuel cell membrane-electrode assembly is provided. The heat treatment apparatus includes a hot press installed on upper and lower sides of feeding path to move in the vertical direction on a frame and which presses the electrode catalyst layers on upper and lower surfaces of the membrane-electrode assembly sheet. A plurality of gripper modules are installed at set intervals in a base member along a feeding direction of the membrane-electrode assembly sheet, and selectively grip both side edges of the membrane-electrode assembly sheet. A driving unit reciprocally moves the base member in a direction perpendicular to the feeding direction of the membrane-electrode assembly sheet and in the feeding direction of the membrane-electrode assembly sheet.

摘要： Provided are a system for manufacturing dispersion liquid of carbon nanotubes and a method of manufacturing a dispersion liquid of carbon nanotubes using the same. The system includes; a mixing device supplied with solvent and carbon nanotubes, and storing a admixture of the solvent and the carbon nanotubes; a first dispersion device connected to the mixing device, performing a primary dispersion of the carbon nanotubes by an operation of a rotor and a stator, and then performing a secondary dispersion to form bent portions in the carbon nanotubes while discharging the carbon nanotubes through penetration holes of the stator; and a second dispersion device performing a tertiary dispersion of the carbon nanotubes to selectively cut the bent portions of the carbon nanotubes by irradiating a laser when the secondarily dispersed admixture recirculates to the mixing device.
