    This thesis is about the production of non noble metal catalysts for the oxygen reduction reaction in fuel cells. Therefore, a novel dual plasma process is developed, constructed and the so-produced films are analysed by various electrochemical (CV, RDE and RRDE) and structural methods (SEM, EDX, IR, XPS, conductivity, XRD, NEXAFS, EXAFS and TEM). It is shown, that by doing this, non noble metal catalysts could be produced without the need of a high temperature treatment. Furthermore, the catalytic activity obtained is superior to that of chemically produced metal-polypyrrole films.
