Abstract

Polymer conductor plate is a type of conductive material made of polymer material that has the ability to conduct electricity. This conductive polymer material generally consists of polymers that have been modified or mixed with conductive materials such as carbon, metal, or other materials to increase their electrical conductivity. Polymer conductor plates are found in fuel cells. Fuel cell is an energy conversion device, working like a battery, where both produce electricity from the electrochemical reaction process. Proton Exchange Membrane Fuel Cell (PEMFC) is a type of fuel cell suitable for self-generation and stationary applications. Graphite is a carbon core that is an electrical conductor used as an electrode material in electric lights, Aluminum is one of the most widespread chemical elements in the outer 16 km of the earth's crust. This research makes polymer conductor plates made from composites. Graphite provides the primary conductivity, aluminum adds conductivity and structural strength, and epoxy resin bonds all components while providing additional strength and durability. The purpose of this research is to determine the effect of composition on polymer conductors. The research was started by conducting a literature study, then making composite plates with the composition of AL 40% - G 40% - R 20%, AL 50% - G 30% - RE 20%, - AL 30- G 50-RE 20% (composition fraction). From the results of this study, it was found that the high electrical conductivity value in specimen 1 with a composition ratio of 40:40:20 with a value of 0.486 S.cm-1 and specimens that have high bending strength are specimen 2 which is 5.5N/mm2.
