Sulfonated fluoroblock copolymer membranes for direct methanol fuel cell applications
This investigation studied the transport properties of several fluorinated sulfonated membranes for direct methanol fuel cell applications. First, Nafion® membranes were processed with supercritical fluid (SCF) CO2 and ...
Functionalization and characterization of Sulfonated Poly (Styrene-Isobutylene-Styrene) membranes for fuel cells and specialty separation applications
In this study, the transport properties of poly(styrene-isobutylene-styrene) (SIBS) block copolymer were determined as a function of sulfonation level (0-94.9 %), counter ion substitution (Ba+2, Ca+2, Mg+2, Mn+2, Cu+2, ...
