PFSA membrane is better connected than that in Nafion. This signature of better coimectivity of aqueous domains in SSC at intermediate hydration level shown for the small molecular weight chains (trimers), is also observed for the simulations of the chains composed of 15 repeat units as depicted in Fig. 10. In Fig. 9(c), the high value of Ro (4.5 A) has shifted all the curves to larger cluster sizes. Still, where there is a difference between the two polymer electrolytes, SSC PFSA membrane shows a more connected aqueous domain. 

In a recent patent application, Angell et al. described a series of alkylammonimn PILs, which are potentially useful as nonaqueous electrolytes in high-temperature polymer membrane fuel cells. The PILs investigated were stable to temperatures between 200 and 250 C, had conductivities comparable to aqueous solutions, and could be enhanced through the addition of a base with a pA a value intermediate between that of the acid and the base. ...
