Nové katalyzátory pro palivové články

Catalysts for Fuel Cells by Roman Fiala and Vladimír Matolín.

The current heavy traffic causes serious air pollution problems, and in addition the sources of conventional fuels would be worked out soon. Hydrogen represents an alternative carrier of energy which can be produced and distributed worldwide. The efficient way how to transform hydrogen to electricity is a use of fuel cells where electricity is produced using chemical reactions. In case of very promising proton exchange membrane fuel cells the chemical reactions are catalysed by catalysts which are usually made from noble metals. Therefore development of novel cheaper catalysts is crucial for future massive utilisation of such source of clean energy.
