This research can be seen as part of the study of a new protonic
conducting membrane for fuel cells, with the aim of reducing
costs, without penalising their efficiency.
Using sulphonated polymers with a high resistance to thermical
oxidation is one of the ways considered to be capable of
bringing results to good applicatio.
In this paper is reported a study of synthesis and preparation of
new proton exchange membrane (PEMs) for FC.
In the first part is described the sulfonation and
caharacterisation of PEEK-WC, a particular type of poly(ether
ether ketone), while in the second part is reported the synthesis
of poly(aryl ether ether ketones) which were prepared by
aromatic nucleophilic substitution reaction of polycondensation
from bisphenols and 4,4'-difluorobenzophenone in the presence
of a base.
