The aim of the project was to determine the fundamental relationships between formation conditions, structure, molecular dynamic and functional properties (proton conductivity, thermo stability) of proton conducting membranes for hydrogen fuel cells based on modified hybrid materials. Using sol-gel method the approaches were developed to synthesize the new proton conducting polymer electrolyte membranes (PEM) based on polyionene, tetraethoxy silane, phosphoric acid and various organic and inorganic modifiers |
