MAProCon - New macromolecular architectures and functions for proton conducting fuel cell membranes

The purpose with the project ‘New macromolecular architectures and functions for proton conducting fuel cell
membranes’ involved research in how the chemical and morphological composition of polymer electrolyte membranes
(PEM) for fuel cells (FC) could be improved in relation to existing PEM.
‘State of the art’ PEM is typically a fluoropolymer (Teflon based), which is both expensive, mechanically fragile and has
a limited operational window with respect to temperature. The research has resulted in new structures both with and
without fluor with a wider temperature window and good mechanical strength. Improved low temperature operation, < 0°
C, has been facilitated, but also high temperature operation, > 100°C, looks promising. The PEM may be used in both
hydrogen- and direct methanol FC’s in active as well as passive FC systems. The research has resulted in 2 patents and is
being continued in another project. The research may strengthen the stride towards the fossil free society.
