Publikováno v: Angewandte Chemie (International ed. in English). 56(36)

Highly active and durable oxygen reduction catalysts are needed to reduce the costs and enhance the service life of polymer electrolyte fuel cells (PEFCs). This can be accomplished by alloying Pt with a transition metal (for example Ni) and by elimin

Publikováno v: ECS Transactions. 50:2163-2174

Alkaline membrane fuel cells (AMFCs) are attracting increasing attention owing to recent developments in anion-exchange membranes and non-noble-metal O2-reduction catalysts. Despite these promising improvements, the sluggish kinetics of the H2-oxidat
