At the present time, I'm working on the development of novel electrode materials based on thin films of conductive polymers as polypyrrole (PPy) and polyaniline (PAni) that I then modify by inserting metal particles (Pd, Au, Pt...). The final material is a composite film with homogeneous microstructure and high electrochemical properties. I would like to use these materials for fuel cell applications. So, at the laboratory scale, what kind of techniques should I start with?
