Abstract

Sluggish oxygen reduction reaction (ORR) in cathode electrode is the most common problem in Proton Exchange Membrane (PEM) fuel cell systems. In this study, the ORR behaviours of a half-cell in the cathodic part were investigated which had an impact on its catalyst activity. The electrode was synthesized from multi-walled carbon nanotubes (MWCNT) supported platinum (Pt) catalyst, assigned as MWCNT/Pt, using an impregnation method. In this case, the hexachloroplatinic acid (H 2 PtCl 6 .6H 2 O) acts as a Pt metal catalyst precursor. The PTFE (polytetrafloro-ethylene) was also used as sub-supporting material with MWCNT to produce MWCNT/PTFE composite. The Pt is deposited onto the surface of MWCNT/PTFE composite which forms MWCNT/PTFE/Pt electrode. Using CV and RRDE techniques, the electrochemical phenomena of MWCNT/Pt and MWCNT/PTFE/Pt electrodes in the 0.1 M KOH electrolyte solutions were analysed and compared. The electron transfer (n) from the K-L plot was recorded as 3.89 and 3.77 for MWCNT/Pt and MWCNT/PTFE/Pt electrode respectively. Based on the chronoamperometric analysis, the MWCNT/PTFE/Pt was found to be more stable than MWCNT/Pt. Therefore, the MWCNT/PTFE/Pt electrode may be recommended for PEM fuel cell application considering its electrochemical activity.
