Polybenzoxazine-Poly(2,5-benzimidazole) (PBOA-ABPBI) Membranes via a PPA Sol-Gel Method for High-Temperature PEM Fuel Cell Applications |
| 초록 |
Polybenzoxazine-poly(2,5-benzimidazole) (PBOA-ABPBI) as PEMs were prepared via a PPA sol-gel method. The presence of PBOA in ABPBI membrane enabled to improve the chemical stability and overall efficiency of ABPBI without sacrificing thermal and mechanical stabilities even when such membranes were highly doped with phosphoric acid solution. The covalent linkages between PBOA and ABPBI seems to be formed when BOA was polymerized.Maximum PA content of PBOA-ABPBI membrane was enhanced up to 91 wt.%, resulting in high proton conductivity above 0.14 S cm-1 at T=150 oC and anhydrous conditions. The cell voltages of MEA at 150 oC were around 0.65 V at 0.3A cm-2. |
