Incorporation of ACNTs in SPEEK matrix ameliorates electrochemical power density, durability in proton exchange membrane fuel cells working with low relative humidity |
| 초록 |
Amine functionalized carbon nanotubes (ANCTs) are employed as the potential proton conducting material in the sulfonated poly (ether ether ketone) (SPEEK) matrix. ACNTs tubular like backbone structure make ∏-∏ stacking with SPEEK aromatic chains; thereby provide extended mechanical strength. Whereas, amino functional groups on surface of ACNTs generate acid-base interactions with sulfonic groups on SPEEK chains, which improves the proton conductivity under low relative humidity. The structural, morphological, physiochemical and electrochemical properties of SPEEK/ACNTs and were explored and compared the obtained results with bare SPEEK. The proton conductivity of SPEEK/ACNTs is found to be few fold better that of bare SPEEK under 20% RH. Consequently, the PEMFC performance of SPEEK/ACNTs is observed to be better than that of bare SPEEK under 20% RH at 60 ˚C. While operate the long-term PEMFC durability around 50 h under identical condition, the SPEEK/ACNTs retain reasonable voltage. |
