Abstract

Polymer Electrolyte Membrane Fuel Cell (PEMFC) is one of alternative energy to replace fossil energy for automotive. Bipolar plate is one of the components in PEMFC constituted a crucial component that collects and transfers electron from the anode to the cathode. This research focuses on material selection of composite based on polymeric matrix using carbon and copper reinforcements as bipolar plate material. The main discussion in this research is to analyze the addition of volume fraction of multiwall carbon nanotube (MWCNT) reinforcement used from 0.1 wt%, 0.5 wt% to 1 wt% and the addition of volume fraction of copper reinforcement used from 0.1 wt%, 0.2wt% to 0.5wt%. The material characterizations include electrical conductivity testing and functional groups analysis using Fourier Transform Infrared Spectroscopy (FTIR). It is found that the effect of MWCNT and copper addition increased electrical conductivity properties. The electrical conductivity increased up to 8.57 S/cm for bipolar plate containing highest volume fraction of MWCNT and 15.62 S/cm for bipolar plate containing both MWCNT and copper. The FTIR analysis shows that ester groups are obtained during the mixing process indicated the reaction between PP-g-MA as compatibilizer and the MWCNT are occurred.
