报告摘要：

The electrode structure plays a critical role in controlling the charge and mass transfer performance, thus determining whether the intrinsic catalytic activity of the electrocatalyst could be fully transported to practical electrodes or not during the operation of polymer electrolyte fuel cells. Electrochemical engineering research is required to further understand the influence mechanisms for reducing different overpotentials to bridge the gap between the highly active electrocatalysts and poor power performance devices. This talk will introduce our design of ordered electrodes based on Pt nanowire arrays for low temperature fuel cells to achieve large current density operation, discussing the lessons learnt during the thin film electrode fabrication, from nanostructure growing for tuning the electrode structure, the surface modification using functional Pd nanoseeds and plasma treatment, and alloying to boost the electrode activity and durability.
