Abstract
⺠Degradation on Pt/Nafion is investigated by feeding H2 and O2 in anode side of PEFC. ⺠Generated solution has HF 5.0 Ã 10â 6 mol·lâ 1 of HF, slightly small number as product of degradation. ⺠Using DFT to study the dissociation of trifluoromethanesulfonate (TFMS) as a Nafion model ⺠H and OH radicals induce the degradation of TFMS and formation of HF, CF2O and SO3H. ⺠The degradation of TFMS is affected not only by BDE but also by the behavior of fluorine.
