The composite membranes based on sulfonated graphene oxide (sGO) / sulfonated poly(arylene ether sulfone) (sPAES) were fabricated for the unitized regenerative fuel cells(URFCs). Due to the incorporation of sGO, the number of sulfuric acid functional groups (-SO3H) were increased in the composite membranes. So composite membrane shows highly phase-separated morphology in the AFM image, which influence on the proton conductivity and water uptake. Additionally, the performance of URFC using a sGO/sPAES membrane was confirmed in the unit cell test fixture. |
