"The development of new materials which can be utilised in membrane electrode assemblies (MEAs) for polymer electrolyte membrane fuel cells (PEMFCs) has received considerable attention during the last decade. An ideal catalyst support conducts electrons as well as protons, and is permeable to gases and water. This kind of alternative for catalyst support represent between others the conducting polymers (CP), like polypyrrole. One of the methods of CP/Nafion composites preparation proposed in the literature is hot?pressing, which is similar to the conventional manufacturing methods. More appropriate than merging the presynthesised CP films with the PEM seems to be synthesis of the CP directly on the PEM surface. This minimises the risk of composite degradation and lowering the performance of the resulting MEA. Since PEM is not an electronic conductor, direct electrosynthesis of the CP film on its surface is not possible. Therefore chemical polymerisation was used. Here employed preparation method is ac"@en . . . "5" . "299" . . "Synt\u00E9za a charakterizace polypyrrolov\u00E9ho filmu na perfluorovan\u00E9 sulfonovan\u00E9 membr\u00E1n\u011B typu Nafion" .
