Electrodeposition of Nanostructured Platinum Cluster on Gas Diffusion Layer (GDL) for Polymer Electrode Membrane Fuel Cell (PEMFC)
The pulse electro-deposition processes created the nanostructured Pt cluster directly on the surface of gas diffusion layer (GDL). By localizing platinum on the surface of a gas diffusion layer (GDL), it is possible to decrease the thickness of the catalyst layer and increase the efficiency of platinum usage. The Pt cluster was well dispersed in GDL and composed of Pt nanosheet. The growth mechanism was carefully monitored. By increasing the current density for pulse electrodeposition, the size of Pt cluster was decreased, result in the enhancement of ESA.
