A fuel cell, a device transforming directly the
chemical energy into electricity through a chemical reaction, is a
source of clean energy in the future. Direct Methanol Fuel Cell
(DMFC), uses a proton exchange polymer electrolyte which one
of the key components developed to realize the
commercialization of fuel cells in transportation and portable
equipment. Poly Ether Ether Ketone (PEEK) is a thermoplastic
material that has a combination of physico-chemical and good
mechanical properties. The introduction of sulphonic acid groups
into the polymer chain is an easy strategy to improve the
properties of PEEK. This research aims to study the effect of
time and the temperature of sulfonation in the fabrication of
sulfonated PEEK on the membrane characteristics such as water
uptake, methanol permeability, Ion Exchange Capacity (IEC),
degree of sulfonation and proton conductivity. The results
indicated that sPEEK was potential candidate as proton
conductive membrane for application of DMFC due to
enhancement of proton conductivity although the methanol
permeability also increases proportional with IEC or DS.
