Perfluorosulfonic acid ionomer – silica composite membranes prepared using hyperbranched polyethoxysiloxane for polymer electrolyte membrane fuel cells

We report on the preparation and characterization of perfluorosulfonic acid ionomer (PFSA) – silica composite membranes using hyperbranched polyethoxysiloxane (PEOS) as silica precursor. The membranes were formed via an in situ sol–gel process of PEOS in a PFSA solution and subsequent solution casti...
