Chemically sustainable fuel cells via layer-by-layer fabrication of sulfonated poly(arylene ether sulfone) membranes containing cerium oxide nanoparticles |
| 초록 |
To facilitate further commercialization of PEMFC, decomposition of the polymer electrolyte membrane needs to be solved. Functional sulfonic acid group grafted onto PAES by sulfide linkages to prevent degradation of functional groups was synthesized. On the other hand, CeO2 particles were prepared with a size of 5–7 nm for its radical scavenging ability. The durable layer membrane of 100 μm thickness containing CeO2 spheres on both surface layers was successfully fabricated. The proton conductivity revealed that the CeO2 nanoparticle size lower than 5–10 nm would not affect the proton conductivity of the layer membrane. The polarization curves after 100 h of OCV degradation test demonstrate that the maximum power density of SPAES140-4CeO2 membrane dropped from 363.67 to 295.43 mW cm-2, while that of the pristine SPAES140 membrane significantly decreased from 378.59 to 230.48 mW cm-2. |
