Abstract
Fuel cell is an alternative energy generator that replaces conventional energy plants that use fuel oil with the basic principle of electrochemistry by converting chemical energy into electricity. With the recent oil crisis, alternative energy is needed for a cheap and environmentally friendly future. To solve the problem, composite polymer electrolyte membrane fuel cell can be one solution. In this study aims to obtain a good electrical conductivity value and obtain an optimum composition of the mixture using silica material as a matrix, graphite powder as the main component and bonding epoxy resin. Composite pellets with a composition of 10%:50%:40%, 10%:60%:30% and 10%:70%:20% (fraction volume) are obtained through cold pressing compression at pressures of five (5) tons. In this study also studied the influence of composition on characterization which includes testing roughness and observation of microstructures. From the results of this study, it was obtained that the high electrical conductivity value in the sample three (3) with a composition ratio of 10:70:20 with a value of 49.21 S/cm and a low surface roughness value in the sample (1) with a composition ratio of 10:50:40 with a value of 5.37 μm and the results of observation of the microstructure of the sample (3) with a composition comparison of 10:70:20 seen that graphite carbon has begun to spread, this is due to the content of carbon graphite is more dominant compared to the binder, because silica sand is so smooth that the naked eye silica sand will be difficult to see because it has fused with resin, this indicates a large graphite carbon factor makes this sample the highest value in conducting electric current.
