Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

Carbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

INTERFACE PHENOMENA IN PROTON EXCHANGE MEMBRANE FUEL CELLS

, 2011
Two phase flow phenomena is a critical issue in Proton Exchange Membrane Fuel Cell (PEMFC) development. Two main classes of PEMFCs, direct hydrogen fuel cell (DHFC) and direct methanol fuel cell (DMFC) have similar problem caused by two phase flow. Both the water in cathode (DHFC and DMFC) and CO2 in anode (DMFC) cannot be removed efficiently will ...
