Preparation and characterization of composite membranes based on sulfonated PEEK and AlPO4 for PEMFCs
VS Rangasamy, S Thayumanasundaram, N De Greef… - Solid State Ionics, 2012 - Elsevier
Sulfonated poly (ether ether ketone)(PEEK) and their composites are considered one of the
most promising alternatives for Nafion, the industry benchmark for electrolytic membranes in
proton exchange membrane (PEM) fuel cells. In the present study, PEEK was non-
homogeneously sulfonated using concentrated H2SO4 at different temperatures (room
temperature, 60° C, and 80° C) and time durations (5, 7, 48, and 72h). Composite
membranes of SPEEK with different weight ratios of AlPO4 synthesized by sol–gel were also …
