摘要：
In the presented works different methods of preparation of functionally graded gas diffusion electrodes (GDE) for fuel cell and electrodialysis application were investigated. High electrochemical performance with a low platinum catalyst content of only 0.1mg/cm(2) was achieved. The new GDEs are superior to commercial ones with five times higher platinum content due to their optimized pore structure and improved distribution of catalyst and ion conductive polymer.
