- •
Pt
Au/MWCNT was synthesized by reverse microemulsión method.- •
Pt
Au/MWCNT and Pt/C were characterized by microscopic and spectroscopic techniques.- •
Both materials were studied as catalysts for ORR by electrochemical techniques.
- •
Catalysts were used to prepare MEA's, the performance in fuel cell was evaluated.
- •
Maximum power densities were 625 mW cm−2 for Pt
Au/MWCNT and 355 mW cm−2 for Pt/C.
