New type of membrane electrode assembly based on Nafion membrane and polypyrrole

Popis výsledku v původním jazyce

With intensive development of low temperature fuel cell of type PEMFC there is an effort for minimization of catalyst load and for maximal utilisation of fuel. First problem is connected mainly with the catalyst itself and catalyst support material. Losses of the fuel by its permeation through the solid polymer membrane can be minimised by the modification of the membrane material and/or by the modification of membrane surface by an additional layer. In a modern PEMFC construction are electrodes locateddirectly on membrane surface. This composite so?called membrane electrode assembly (MEA) represents the crucial component of PEMFC. As polymer membrane material is widely used the Nafion (DuPont). In a typical present PEMFC electrode carbon is used as asupport. Teflon in a mixture with Nafion serves as a binder. Conducting polymers (CP) represent an alternative to this electrode construction. Polyaniline and polypyrrole (PPy) are the materials most often referred to in the literature. M
