摘要： A method for manufacturing a gas diffusion layer for a fuel cell wherein carbon nanotubes are impregnated into Korean paper, thereby enhancing electroconductivity, and a gas diffusion layer manufactured thereby. The method for manufacturing a gas diffusion layer for a fuel cell which is to manufacture a gas diffusion layer as a constituent member of a unit cell in a fuel cell, includes a support preparation step of preparing a support with Korean paper; a dispersion preparation step of dispersing a carbon substance in a solvent to form a dispersion, a coating step of coating the support with the dispersion, and a thermal treatment step of thermally treating the dispersion-coated support to fix the carbon substance to the support.

摘要： In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

摘要： A driving system of a driving motor is proposed. The system includes: a stator having slots at which coils are wound; a first inverter connected to first ends of the coils of the stator; a second inverter connected to second ends of the coils of the stator; and a stage switch circuit configured to control an electrical connection between the second ends of the coils of the stator and the second inverter. In particular, the coils include a first coil set connected to an output terminal of the first inverter, and a second coil set connected to an input terminal of the second inverter. Currents having the same phase or currents having different AC phases are applied to the first coil set and the second coil set wound at the slots by controlling on and off of the stage switch circuit.
