| Description
| - Fuel cells are extremely attractive alternative energy conversion devices for transportation and portable applications. Among several types of fuel cells, polymer electrolyte membrane fuel cells (PEMFC) have been regarded as promising options for electrical vehicles. The vital component of PEMFC is a proton conducting membrane. The state-of-the-art technology is mostly based on perfluorinated membrane materials, such as Nafion(R) (DuPont, USA), Flemion(R) (Asahi Glass, Japan) and Aciplex(R) (Asahi Kasei, Japan). Because of involvement of expensive fluorine chemistry, the membrane material costs represent (in addition to the catalyst) the major contribution to the membrane electrode assembly (MEA) price. Much effort has been focused during the last decades on the development of new, lower cost membrane materials possessing suitable properties. Mainly homogeneous membranes were studied for this purpose so far. Another possibilty, however, represents the application of heterogeneous ion-exchange mat

- Palivové články představují nový a velice perspektivní energetický zdroj. Poslední dobou vzrůstá zájem o využití nízkoteplotních palivových článků; a to specielně typu PEM (Proton Exchange Membrane). Kapalný elektrolyt v tomto typu palivového článku je nahrazen iontově výměnnou membránou. V současné době jsou nejvíce využívány perfluorovaná membrány se sulfoskupinami v postraních řetězcích, jako např. membrána Nafion(R) (DuPont, USA), Flemion(R) (Asahi Glass, Japan) a Aciplex(R) (Asahi Kasei, Japan). Membrány tohoto typu jsou však drahé, což brání jejich široké aplikaci. Je tedy žádoucí nalézt vhodnou, levnější alternativu membrány Nafion s obdobnými vlastnostmi. Jako testované materiály se objevují pouze homogenní membrány. Dalším alternativním řešením jsou heterogenní membrány, u kterých jsou částice iontoměniče fixovány v inertní matrici. Homogenní membrány vykazují dobré elektrochemické vlastnosti, ale horší mechanickou odolnost, na rozdíl od membrán heterogenních. V této práci byla studována (cs)
