In this study a promising approach for a novel fuel cell catalyst layer is shown using films of carbon nanotubes (CNTs) formed by the layer-by-layer (LbL) method. A special focus is on the dispensing procedure of CNTs in water what is one of the most essential steps to
realize monolayers in a reproducible way as targeted in LbL. Furthermore, the platination of the tubes is demonstrated
using the reduction of platinum salt in ethylene glycol resulting in a sufficient distribution of nanosized particles. Finally, ultrathin films based on the functionalized nanotubes are investigated with atomic force microscopy, showing promising results for the future use as catalyst layer.
