“Approximate” Pt layers hold great promise to be highly active and durable oxygen reduction reaction (ORR) catalysts. Electrodeposition of such layers on relevant catalyst supports, for example TiOx, requires the application of a “Pt-on-Pt” d

An “approximate” Pt monolayer is a desirable morphology for oxygen reduction reaction (ORR) catalysts with high mass activity. Such structures can, reliably, be synthesized on gold by monolayer-limited CO- or over-potential deposited hydrogen (Ho

Methods of protecting Pt(-alloy) particles against dissolution during fuel cell operation have recently gathered attention. Titania as a promising Pt catalyst support has its own built-in protection mechanism, called strong metal-support interaction

Very thin Pt layers on inexpensive substrates are promising oxygen reduction reaction (ORR) catalysts for polymer electrolyte fuel cells (PEFCs). TiOx is considered a suitable substrate but shows problems with conductivity, thus masking chemical effe

Forming platinum monolayers on less-expensive materials is an ingenious way to enhance the mass activities for oxygen reduction reaction (ORR) and decrease the amount of this scarce and precious metal in fuel cell technology. Previously, we observed

Platinum layers show higher specific oxygen reduction reaction (ORR) activities than nanoparticles, and smooth monolayers of platinum on polycrystalline gold have been achieved by electrodeposition from CO-saturated solutions. Since Pt monolayers are

For improving the efficiency and reducing Pt use in polymer electrolyte fuel cells, it is essential to improve the catalytic activity per Pt mass for oxygen reduction reaction (ORR) in the cathode. In addition, recent studies have demonstrated that a

Cathode catalyst layers for polymer electrolyte fuel cells (PEFC) with ionomer nanofiber scaffoldings (iNFS-CL) are fabricated by the electrospinning method, and their performances and elemental properties are comprehensively investigated. The cells
