Polymer electrolyte membrane based on functionalized mesoporous silica for PEM fuel cells

To develop polymer electrolyte membranes from sulfonated poly (phthalazinone ether ketone) (SPPEK), a novel polymer membrane consists of SPPEK and SBA-Ph-SO3H mesoporous silica (phenyl sulfonic acid grafted SBA-15) were prepared by solution casting method. The prepared membranes displayed a high proton conductivity of 110 mS/cm at 80 °C. According to the PEM fuel cell results, a high current density of 0.81 Acm-2 at 0.5 V, 80 °C and 90% RH, the prepared membranes have a high potential for using as an appropriate membrane in the fuel cells.
