The increasingly evident consequences of climate change are a major motivation for the development of low-carbon technologies, among which fuel cells, using hydrogen as fuel, hold great promise. One of the obstacles to the wider commercialization of the technology is the use of expensive and rare platinum in catalysts, which is why effort goes into trying to reduce the amount of platinum used while preserving the relevant properties of these materials. For the oxygen reduction reaction, one of the reactions in a fuel cell, we use catalysts with alloyed nanoparticles containing platinum and cheaper transition metals. Since certain defects in the nanoparticle structure can occur during the preparation of the catalyst, the effects of all aspects of the structure on the performance in the fuel cell need to be studied in detail.
