Abstract

Bipolar plate is one of the key parts in the fuel cell technology with the advantages of a higher electrical conductivity and mechanical properties are high. Injection molding is one of the manufacturing method that being used in the manufacture of bipolar plates. The critical powder loading and rheological properties of the feedstock are an important factor in the process of injection molding in the manufacturing process of bipolar plate. The critical powder loading feedstocks with a mixture of polypropylene and graphite have been conducted with the torque method test. The appropriate critical powder loading the using a graphite filler material was produced with the composition of 75 % the weight of an optimum load and 25 % weight of polypropylene. The rheological studies have also been carried out using capillary test for determining critical loading powder by increasing the viscosity of the feedstock. The test results showed that the rheological properties of the feedstock with optimum powder loading to exhibit pseudoplastic properties are suitable for injection molding process with the n less than one.
