Our doctoral student Lucinda Blanco Redondo presented her contribution named "Ir-decorated Pt nanoparticles for unitized regenerative fuel cell catalyst" at Hydrogen Days 2021. In her talk, she described a relatively easy procedure to prepare bimetallic nanoparticles that show remarkable catalytic activity in both oxygen reduction and oxygen evolution reactions, compared to commercial catalysts. Besides the synthesis and activation procedures, Lucinda presented her and her colleagues' results of structural analyses, activity measurements, and durability tests. The results make these "raspberry-like" nanoparticles a promising candidate for the oxygen-side catalyst in unitized regenerative fuel cells.
Lucinda's presentation has been elected the best student talk at the event, which hosted 38 oral presentations and 15 posters.
Hydrogen Days is a yearly international conference organized by the Czech Hydrogen Technology Platform (HYTEP). This year was the 11th one and was—for obvious reasons—held online.
