This project will systematically study the novel fuel cells hybrid catalyst materials fabrication characterization and catalytic mechanism based on the nanoscale phosphide catalytic promoters, probe the synergistic effects between the catalytic active ingredient and promoter with the optimized structure-activity relation and long-term catalytic mechanism, form a kind of novel hybrid catalyst design concept by combining the catalytic activity and stability, and finally develop the relevant high-performance fuel cell catalyst fabrication technology. This study will screen several kinds of long-term highly active catalyst system and deeply understand the relationship in terms of the catalytic activity, stability, structure, composition with the help of the fuel cell test and in situ characterization technology to propose a novel approach of increasing the catalyst utility, and the results will be instructive to the large-scale catalyst fabrication for potential commercial application.
