In Honor of the 2021 R.H. Wilhelm Award Winner I (Invited Talks)
Wednesday, November 8, 2023 - 9:36am to 9:52am
In this talk, I will describe our recent research endeavors toward the development of efficient Ni-based HOR catalysts for practical HEMFC anodes. First, we briefly highlight the important merits of HEMFC technology and why Ni-based materials are appealing for alkaline HOR catalysis. Critical innovations in the design of Ni-based nanostructured and bulky catalysts were then discussed, showing their great promise to catalyze alkaline HOR that traditionally relied on PGMs. To demonstrate utility, performances of the elaborately designed Ni-based catalysts under realistic fuel-cell conditions were examined, along with an initial effort to develop CO-tolerant HEMFC anode. I will conclude this talk by outlining future research directions that allow access to next-generation PGM-free HOR catalysts for advanced HEMFCs.
