Abstract

Composites are a number of multi-phase systems with the combined properties of a matrix (binder) and reinforcement (reinforcement material). Graphene oxide can be applied to bipolar plate because graphene oxide has a high proton conductivity with the addition of epoxy resin as a binder (matrix). Fuel cell is an electrochemical that can convert chemical energy directly into electrical energy through a reaction between gas fuel (hydrogen) and air (oxygen) without having to be burned which can cause pollution. This study aims to obtain a good conductivity value and obtain an optimum mixture composition using Graphene Oxide as a filler with an epoxy resin binder with a composition of 60%: 40%, 70%:30%, 80%:20% using Compression Printing method with high strength. press 5ton for 30 minutes. This study also analyzes the effect of composition on the compressive strength test and microstructural analysis. In this study, the highest electrical conductivity was found in three (3) specimens with a composition of 80%:20% with a value of 65.62 S/cm and the highest compressive strength test value was found in the first test object (1) with a composition of 60%:40. %. value 6.61 MPa.
