“…Indeed, any commercialization will need to be based on lowering the cost by reducing the platinum loading, as well as improving cell performance and durability [ 3 , 4 ]. Several approaches have been attempted in this context for optimizing operating conditions [ 5 ], with various effects having been studied [ 6 , 7 ]. In particular, significant effort has been directed at reducing the platinum load in the catalyst layers (CLs) without compromising cell performance [ 8 , 9 ].…”
