An electrochemical route to prepare Pd nanostructures on a gas diffusion substrate for a PEMFC

- Preparation of a catalyst layer of Pd on a gas diffusion substrate for polymer electrolyte membrane fuel cell.
- Innovative nanostructures of Pd were obtained by electrodeposition.
- The star-cubic-like structure has the highest catalytic activity for the ORR.
- Performance of MEA is high compared to literature data on MEA with Pd catalyst on the cathode.
