Morphology and electrochemical properties of Pd-based catalysts deposited by different thin-film techniques

- Pd was deposited on carbon/PTFE GDL substrate by electrodeposition and sputtering.
- Electrochemical properties were correlated to surface morphologies of deposits.
- Sputtered samples showed cauliflower-like clusters and best EAS after CV cycling.
- Pd hydride was formed in electrodeposits with flower-like clusters structure.
