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).
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
