Operational cost issues have been concern in Proton Exchange Membrane Fuel Cell (PEMFC). Especially on cathode electrodes that using platinum as its catalyst. Platinum is expensive and it can lead to electrolyte poisoning, Non-platinum Group Metal (Non-PGM) catalysts was chosen to overcome those problems above. A Ti-Co/C catalyst was prepared using impregnation-reduction method and characterized using cyclic voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS) methods. This study aimed to compare the result between matrix carbon Vulcan XC-72R and Dots carbon which was applied to Ti-Co/C catalyst, also to compare the method of coating catalyst on GDL layer were Doctor Blade and spraying methods. The result was confirmed that Ti-Co/C with the ratio of Ti:Co 50:50, using Dots carbon as its matrix and spraying method preparation has ECSA value and conductivity respectively 28.72 cm2/g and 0.16 x 10-3 S/cm, those were the highest value than another method. The conclusion of this study was non-platinum catalyst Ti-Co/C which used Dots carbon as a matrix and the spraying method showed a good response as a cathode catalyst of PEMFC
