Decorated core-shell bimetallic nanoparticle electro-catalysts for proton exchange membrane fuel cells

One of the most significant barriers for the commercialization of Proton Exchange Membrane Fuel Cells (PEMFCs) is the cost issue. It mainly comes from the high usage of precious metal Platinum (Pt) and its alloy as the electrocatalysts due to the low Pt utilization efficiency in the catalyst layers...
