摘要
Perfluorosulfonic acid (PFSA) polyelectrolyte confined in subnanoliter volume within zeolite cladded walls exhibits higher glass transition temperature and excellent tolerance to high-temperature fuel cell operation under dry conditions, generating an order of magnitude higher power density than standard PEMFC.
