PEM Materials

Creating novel proton exchange membranes (PEM) for proton exchange membrane fuel cells (PEMFCs) is a major focus in our group.  We have developed the poly(phenylene) family of polymers as our platform for discovery of new PEM membranes (shown below).


Poly(phenylene)s have proven to be a good platform due to their ability to be synthesized in high molecule weight which facilitates forming thin, robust membranes, their large chemical diversity, good mechanical properties in the solid state, and ability to undergo post modification reactions.

These membranes have been demonstrated in both direct methanol and hydrogen air fuel cells.  See Fact Sheet.
