The water uptake, transport and mechanical properties of organic-inorganic hybrid materials based on sulfonated and silylated, cross-linked polyetheretherketone (called SOSi-PEEK/N, where N is the molar percentage of silylated monomeric units) for application in fuel cells are reported. The mechanic

## Abstract Protonβexchange membranes (PEM), suitable for micro and small sized fuel cells, were obtained by blending sulfonated poly(ether ketone ketone) (SPEKK) polymers with different ionic exchange capacity (IEC). This approach was used to limit the amount of swelling caused by water sorption w
Capillary-induced transport of liquid water inside the porous diffusion media (DM) of polymer electrolyte fuel cells (PEFCs) is strongly dependent on DM pore structure and material properties. As such, excessive liquid in the DM can be expelled more efficiently into flow channels by proper design of
