Sulfonated graphene oxide (SATS-GO) composite membranes for proton exchange membrane fuel cells (PEMFCs) application |
| 초록 |
Sulfonated graphene oxide (SATS-GO) was incorporated into the sulfonated poly(arylene ether sulfone) as a filler to prepare composite membranes for polymer electrolyte membrane fuel cells (PEMFCs). Sulfonated graphene oxide could be obtained by modification of graphene oxide (GO) using sulfonated poly(arylene thioether sulfone) (SATS). The SPAES/SATS-GO composite membranes were fabricated by casting the SPAES and SATS-GO solution mixtures using a doctor blade film applicator. To study the effect of SATS-GO, pristine GO composite membrane was also prepared as a control group. The SPAES composite membranes containing the SATS-GO showed improved chemical, mechanical properties and exhibited high proton conductivity compared to pristine SPAES membrane. At 80°C and 40% RH, SPAES/SATS-GO-2.0 composite membrane exhibited increased proton conductivity of 4.63 mS cm-1 |
