The composite membrane based on sulfonated grapheme oxide(sGO)/ sulfonated poly(ether ether ketone) (sPEEK) was fabricated for the unitized regenerative fuel cells(URFCs). When the content of sGO was high, membrane’s water uptake was highly increased. And the proton conductivity of the composite membrane grew with the incorporation of sGo. It is assumed that the increased proton conductivity is due to the introduction of many proton sources (-SO3H groups of sGO) and good dissociation of sulfuric acid functional groups in a fully hydrated state. Additionally, the composite membrane was performanced in the unit cell test with URFCs. |
