Poly(ether ether ketones) (PEEKs) are sulfonated and used as a binder in the electrode for DMFC studies. The effect of sulfonated PEEK (s-PEEK) binder in the catalyst layer on the cell performance is investigated. The s-PEEK binder in the electrode is found to be more efficient in maintaining long-term stability of the cell performance than the conventional Nafion binder. The cell based on electrode...
For direct methanol fuel cell, blends of vinylidene fluoride-hexafluoropropylene copolymer (P(VdF-co-HFP)) and Nafion were prepared the different equivalent weight of Nafion. The investigations of the blend morphology were performed by means of permeability test, uptake measurement, differential-scanning calorimetry (DSC), and scanning electron microscopy.In the blend membranes, many pores were created...
