Abstract
In this research, the high performance bipolar plate were fabricated by using compression molding. In polymer electrolyte membrane fuel cell (PEMFC), bipolar plate is considered one of the most important components which takes a large portion of stack stock. It has a multi-functional in the fuel cell stack. The fuel cells are the most promising power source in the future because it can provide good energy efficiency, little pollution and little noise. In this project, the raw materials used to fabricate the high performance bipolar plate are Graphite (Gr), Stannum (Sn) and Polypropylene (PP). The Gr and Sn will be used as fillers and PP will be used as binder (Resin).The composition ratio of fillers: binder will be fixed 80%; 20%. But for main-conductive filler ratio of Gr will vary from 70%, 65% and 60%. Meanwhile, the second conductive filler, Sn will vary from 10%, 15% and 20% from the total percentages of fillers (80%). The Polypropylene (PP) will be pulveriser and sieve in order to get 500μ sizes. The fillers material will be mixed with binder material by using the ball mill machine before shaped by using the hydraulic compression molding machine with three different temperature such as 165˚C, 170˚C and 175˚C. The effect of Sn loading and temperatures on the electrical conductivity and mechanical properties of GR/Sn/PP composite have been evaluated. The result shows that density and hardness have meet DoE standard and just electrical property and flexure strength did not meet the DoE, thus due to agglomeration complication and PP does not distribute well in bipolar plate. The maximum value of all testing result are electrical conductivity is 49.65 S/cm, flexural strength is 15.46 MPa, bulk density is 1.960 g/
