Název v původním jazyce

Utilization of Nafion(R)/Conducting Polymer Composite in the PEM type Fuel Cells

Popis výsledku v původním jazyce

The present study focuses on the problem of using conducting polymers (CPs) in proton exchange membrane fuel cell technology. It covers the electrocatalytic properties of the CP/Pt composite, permeability of the CP film for H2, fixation of the compact CPfilm on the top of the Nafion(R) membrane and first results of its utilization in the fuel cell. The electrocatalytic activity of the CP/Pt composite superior to the commercially available carbon supported catalysts reported in the literature has not been proved. The main reason seems to be the very low permeability of the compact CP film for the fuel and the size of the catalyst particles. This may be an advantage with respect to the minimization of the fuel cross over, which represents a serious problem in the direct methanol fuel cell. On the other hand, it may represent a serious danger when taking water management of the fuel cell and possible drying out of the membrane into account. This fact has been recognized and alternative s
