Molecular Conformation of Nafion Ionomer on Electrocatalyst Layer Prepared by Screen Printing Technique

open access: yesInternational Journal of Electrochemical Science, 2014
Preparations of Pt/CNT electrocatalyst layer in colloidal and solution state by screen printing techniques gave different molecular conformation of nafion ionomer. By this technique, low Pt- loaded (0.07-0.1 mg/cm2) and thin electrocatalyst were produced

Using the Palladium as core and Platinum as shell for ORR [PDF]

open access: yesHydrogen, Fuel Cell & Energy Storage, 2014
In this work, electrocatalyst with core-shell structure (Pd as core and Pt as shell on VulcanXC-72R) was synthesis. Not only this structure can reduce the amount of platinum but it also can increase the gas diffusion electrode (GDE) performance in ...
