The development of platinum group metal-free catalysts for the oxygen reduction reaction is central to the implementation of fuel cell technology. Here the authors introduce and analyse a dedicated protocol for platinum group metal-free oxygen reduction reaction catalysts to assess their activity and durability under relevant working conditions.
Catalyst development in academia focuses on performance metrics, giving only secondary attention to costs despite their relevance for commercialization. Here, the authors analyse the properties of a handy and free cost estimation tool that can inform the early stages of catalysis research.
