Paper Title:
Interface Influence on the Proton-Conductivity of Ordered Mesoporous Silica Membranes
  Abstract

As an alternative to a solid-state electrolyte for proton exchange membrane fuel cells (PEMFCs), ordered mesoporous membranes (OMMs) were prepared using a sol-gel technique, followed by a deep-UV irradiation. Structure and impedance spectroscopy analyses revealed that the porous architecture and proton conductivity of OMMs were influenced by the nature of the substrates. Compared with hydrophilic substrate, hydrophobic substrate was beneficial to an accessible porous architecture in the interface layer and an increase of proton conductivity of the whole membrane. The proton conductivity of the OMMs was up to 10-3 S cm-1.
