Composite membranes using highly sulfonated graphene oxide (SATS-GO) for polymer electrolyte membrane fuel cells (PEMFCs) application |
| 초록 |
Sulfonated graphene oxide (SATS-GO) was blended with the sulfonated poly(arylene ether sulfone) as an inorganic/organic filler to prepare composite membranes for proton exchange membrane fuel cells (PEMFCs). Sulfonated graphene oxide could be fabricated by modification of graphene oxide (GO) using sulfonated poly(arylene thioether sulfone) (SATS). The SPAES/SATS-GO composite membranes were fabricated by typical solution casting method. Pristine GO composite membrane was also fabricated as a control group to confirm the effect of SATS-GO. The SPAES composite membranes containing the SATS-GO exhibited improved physicochemical properties and higher proton conductivity compared to pristine SPAES membrane. SPAES/SATS-GO-2.0 composite membrane showed increased proton conductivity of 4.63 mS cm-1 at 80 ℃ and 40% RH. |
