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： An open-cathode-type fuel cell system includes hollow fiber membranes, through which moisture contained in unreacted hydrogen discharged from a fuel cell stack is transferred to air flowing into the fuel cell stack, and an aerial vehicle using the same. The open-cathode-type fuel cell system includes a fuel cell stack configured to generate electricity through a reverse electrolysis reaction using hydrogen and air supplied from the outside, a humidifying structure disposed on one side of the fuel cell stack in order to transfer moisture included in unreacted hydrogen, discharged from the fuel cell stack, to air flowing into the fuel cell stack, and a cooling fan disposed on the other side of the fuel cell stack in order to discharge unreacted air, discharged from the fuel cell stack, and cooling air to the outside. Accordingly, the performance of the air-cooled fuel cell system may be improved.
