Method for manufacturing cathode with improved mass transfer capability and cathode manufactured by the method

A method of manufacturing a cathode with improved mass transfer capability comprising:

• step (a) mixing a metal-supported catalyst with an alkane compound having a thiol group and masking a surface of the metal-supported catalyst with the alkane compound having the thiol group by coating;
• step (b) mixing the metal-supported catalyst masked with the alkane compound having the thiol group, with a polymer electrolyte and a solvent to produce a slurry and manufacturing a cathode using the slurry;
• and
• step (c) producing a membrane electrode assembly (MEA) using the cathode, an electrolyte membrane and an anode and applying a voltage to the MEA to remove the alkane compound having the thiol group,
• wherein the voltage is applied to the produced MEA by cyclic voltammetry in step (c).
