Electrochemical surface area (ECSA) is the key factor of analyzing catalyst performance in fuel cell. Good dispersion of platinum(Pt) nanoparticles on Multi-walled carbon nanotube(MWCNT) lead to increase ECSA values. In the present study, we performed Pt deposition process on MWCNT with various PH values to improve ECSA values. Pt deposition process is performed at different PH value. X-ray diffraction (XRD) analysis was performed and Pt particle size on MWCNT was measured. After that, cyclic voltammetry was performed in order to measure the ECSA Acknowledgment :This work was supported by the Manpower Development Pro-gram for Energy & Resources funded by the Ministry of Knowledge and Economy, Republic of Korea.
