While promising results were reported with all of the above systems, especially encouraging direct methanol fuel-cell performance data were obtained with membrane prepared from blends of sulfonated poly[bis(phenoxy)phos-phazene] (SPBPP) and PBI [34]. The effect of FBI content on room-temperature membrane proton conductivity, room-temperature water uptake, and methanol permeability (at 60°) is shown in Fig. 12. 

The direct methanol fuel-cell performance of three polyphosphazene-based membrane systems is presented below. The first system deals with blends of PVDF with either sulfonated poly[(3-methylphenoxy)(4-ethylphenoxy)phos-phazene] (SP3MP4EPP) or sulfonated poly[(4-ethylphenoxy)(phenoxy)phos-phazene] (SP4EPPP), where the membranes were prepared by solution casting mixtures with subsequent crosslinking using electron-beam irradiation (60 MRad). The second membrane system was based on UV-photocrossHnked...
