Abstract:Solid acids, such as CsHSO4 and CsH2PO4, are a novel class of anhydrous
proton-conducting compounds that can be used as electrolyte in H2/O2 and
direct methanol fuel cells. The disordering of the hydrogen-bonded network
above the so-called superprotonic phase transition results in an increase of the
proton conductivity by several orders of magnitude. Unlike conventional
polymer electrolytes, such as Nafion©, proton conduction in the solid acids does
not rely on transport of hydronium ions.
The research described in this thesis is mainly focused on developing protonconducting
solid acid electrolytes for potential use in a micro solid acid-based
fuel cell.
