Special Catalysts Used for Fuel Cells
In the future increasing importance will be placed on hydrogen and fuel cell technology in environmental and energy policies. Besides applications in mobile areas, fuel cell systems are arousing increasing interest in stationary systems, such as the energy supply for households. In the portable field there are already systems ready to be launched on the market for a great variety of applications.
Modern fuel cell technology, such as PEMFC, requires highly efficient electro-catalysts for the coating of membranes.
