- Polymer type’s fuel cell generator are depends on oxidant as fuels. For hydrogen and methanol fuel’s oxidant, there are proton exchange membrane fuel cell (PEMFC) and direct methanol fuel cell (DMFC)‘s type. Each type of fuel cells needs suitable membrane as electrolyte in order to get high density of proton transfer reaction. In this research the conductivity and water uptake of sulphonated polyether-ether keton (sPEEK) with silica modified composite hydrocarbon membrane in various thickness up to 100 μm were investigated. The selectivity of proton transfer reaction had been calculated. In summary, the ionic conductivity showed about 10-2 S.cm-1 to 2 S.cm-1 and water uptake about 30-45 (% w/w). In the thickness between 70 μm to 100 μm, the influence of the thickness membrane on ionic conductivity was increased by two times the ion conductivity. The sulphonated PEEK with silica modified composite membrane have clearly shown as a good candidate for DMFC applications with 90-100 μm thickness and for PEMFC’s is 70 μm.Keywords: Polymer electrolyte membrane, Sulphonated hydrocarbon polymer, Ionic conductivity
