Název v původním jazyce

Poster: Polypyrrole vs. polyanilin as the catalyst support materials in the PEM type fuel cells.

Popis výsledku v původním jazyce

This paper compares properties of polypyrrole (PPy) and polyaniline (PAni) with respect to theirs application in the fuel cell development. The attention focuses mainly on the synthesis and properties of the membrane - conducting polymer (CP) composite as a base of Membrane Electrode Assembly. In the first step the kinetics of PPy and PAni film formation has been followed. The results obtained indicate that the rate determining step is represented by the monomer transport through the CPs films formed onthe membrane surface. Similarly to the monomers, the CP film present on the membrane surface deteriorates methanol permeation through the composite seriously. Permeability obtained for PPy and PAni do not differ substantially and they are lower by approximately two orders of magnitude when compared to the pure Nafion# membrane. From the point of view of possible future application time stability of composites is of a great interest. An attempt was made to compare stability of the electr
