Abstract

A fuel cell is an electrochemical conversion device for generating electricity from the reaction of hydrogen and oxygen. The working principle of a fuel cell is the same as a battery but does not require recharging because it will continuously generate electricity as long as the fuel is fulfilled. Fuel cells are considered more efficient and environmentally friendly because they can generate electricity from the reaction of hydrogen and oxygen which only produces water as a waste product. To overcome this problem, a polymer electrolyte membrane fuel cell composite could be one solution. The lightweight and corrosionresistant nature of the polymer makes it particularly suitable for this application. This study aims to obtain a good electrical conductivity value and to obtain a graphite mixture composition using a local binder, namely epoxy resin. Metal mesh composite plate with composition Graphite 60% : Epoxy Resin 40%, Graphite 70%: Epoxy Resin 30% and Graphite 80%: Epoxy resin 20% (volume fraction) obtained through compression molding process at a pressure of six (6) tons with time 45 minutes. This research also studied the effect of composition on characterization which included bending test and microstructure observation. From the results of this study, it was found that the high electrical conductivity value in specimen three (3) with a composition ratio of 80:20 with a value of 25.0 S.cm-1 with a bending strength of 121.6 MPa.
