THE EFFECT OF STAINLESS STEEL ON THE PROPERTIES OF GRAPHITEPOLYPROPYLENE COMPOSITE FOR BIPOLAR PLATE 24pages.pdf Download (5MB) |
Abstract
Over the past decade, rapid progress has been made in the understanding and development of Conductive Polymer Composites (CPC) as conducting materials. This project is aimed to study the effects of stainless steel (St) loading on the electrical and mechanical properties of Graphite (G)/ Stainless steel (St)/ polypropylene (PP) composite of bipolar plates for polymer electrolyte membrane fuel cells (PEMFC). St is selected as second filler because it offers good electrical conductivity, high bulk thermal conductivities, good corrosion resistance and constant particle shape. The analysis of the G/St/PP composites ratio and the properties of G, St and PP together with the impact of Graphite (G) as a main filler and Stainless Steel (St) as second filler whereas polypropylene (PP) as a binder has been carry out. The impact of fillers on the composite properties was evaluated as well as the ratio of the weight percentage (wt%) of the composite with 80% for multi-filler material and 20% binder material. The St wt % is vary from 5 wt % up to 30 wt % of total wt % of multi-filler materials. After formation of composite through compression molding, the effects of St in G/St/PP composite have been determined through various tests such as electrical conductivity, flexure strength, density and hardness before can be used as composition of G/St/PP composite for bipolar plate. The result showed the analysis for Flexural Strength, Bulk Density and Shore Hardness meet the required characteristics of bipolar plate as in the Department of Energy (DOE). But for electrical conductivity, the results showed a very slight increase which is less than 1 OOS/cm.
