Often nanostructuring leads to enhanced ionic mobilities due to the induced space-charge effects. Here these large space-charge effects occurring in composites of the proton-donating solid acid CsHSO4 and the proton-accepting TiO2 or SiO2 are studied. CsHSO4 is chosen for this study because it can operate effectively as a fuel-cell electrolyte at elevated temperature while its low-temperature conductivity is increased upon nanostructuring. The composites have a negative enthalpy of formation for defects involving the transfer of protons from the acid to the acceptor. Very high defect densities of up to 10% of the available sites are observed by neutron diffraction. The effect on the mobility of the protons is observed directly using quasielastic neutron scattering and nuclear magnetic resonance spectroscopy. Surprisingly large fractions of up to 25% of the hydrogen ions show orders-of-magnitude enhanced mobility in the nanostructured composites of TiO2 or SiO2, both in crystalline CsHSO4 and an amorphous fraction. 000020180 536__ $$0G:(DE-Juel1)FUEK412$$2G:(DE-HGF)$$aGrundlagen für zukünftige Informationstechnologien$$cP42$$x0 000020180 536__ $$0G:(DE-Juel1)FUEK415$$aGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$cP55$$x1 000020180 588__ $$aDataset connected to Web of Science 000020180 650_7 $$2WoSType$$aJ 000020180 65027 $$0V:(DE-MLZ)SciArea-120$$2V:(DE-HGF)$$aCondensed Matter Physics$$x0 000020180 65027 $$0V:(DE-MLZ)SciArea-110$$2V:(DE-HGF)$$aChemistry$$x1 000020180 65017 $$0V:(DE-MLZ)GC-110$$2V:(DE-HGF)$$aEnergy$$x0 000020180 693__ $$0EXP:(DE-MLZ)External-20140101$$5EXP:(DE-MLZ)External-20140101$$eExternal Measurement$$x0 000020180 7001_ $$0P:(DE-HGF)0$$aHaverkate, L.A.$$b1 000020180 7001_ $$0P:(DE-Juel1)VDB90007$$aBorghols, W.J.H.$$b2$$uFZJ 000020180 7001_ $$0P:(DE-HGF)0$$aWagemaker, M.$$b3 000020180 7001_ $$0P:(DE-HGF)0$$aPicken, S.J.$$b4 000020180 7001_ $$0P:(DE-HGF)0$$avan Exk, E.R.H.$$b5 000020180 7001_ $$0P:(DE-HGF)0$$aKentgens, A.P.M.$$b6 000020180 7001_ $$0P:(DE-HGF)0$$aJohnson, M.R.$$b7 000020180 7001_ $$0P:(DE-HGF)0$$aKearley, G.J.Ü$$b8 000020180 7001_ $$0P:(DE-HGF)0$$aMulder, F.M.$$b9 000020180 773__ $$0PERI:(DE-600)2039420-2$$a10.1002/adfm.201001933$$gVol. 21, p. 1364 - 1374$$p1364 - 1374$$q21<1364 - 1374$$tAdvanced functional materials$$v21$$x1616-301X$$y2011 000020180 8567_ $$uhttp://dx.doi.org/10.1002/adfm.201001933 000020180 909CO $$ooai:juser.fz-juelich.de:20180$$pVDB$$pVDB:MLZ 000020180 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000020180 9141_ $$y2011 000020180 9131_ $$0G:(DE-Juel1)FUEK412$$bSchlüsseltechnologien$$kP42$$lGrundlagen für zukünftige Informationstechnologien (FIT)$$vGrundlagen für zukünftige Informationstechnologien$$x0 000020180 9131_ $$0G:(DE-Juel1)FUEK415$$bStruktur der Materie$$kP55$$lGroßgeräteforschung mit Photonen, Neutronen und Ionen$$vGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$x1 000020180 9132_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$aDE-HGF$$bForschungsbereich Materie$$lIn-house research on the structure, dynamics and function of matter$$vNeutrons for Research on Condensed Matter$$x0 000020180 9201_ $$0I:(DE-Juel1)PGI-4-20110106$$gPGI$$kPGI-4$$lStreumethoden$$x0 000020180 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II$$lJCNS-FRM-II$$x1 000020180 9201_ $$0I:(DE-Juel1)JCNS-2-20110106$$gJCNS$$kJCNS-2$$lStreumethoden$$x2 000020180 970__ $$aVDB:(DE-Juel1)135299 000020180 980__ $$aVDB 000020180 980__ $$aConvertedRecord 000020180 980__ $$ajournal 000020180 980__ $$aI:(DE-Juel1)PGI-4-20110106 000020180 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000020180 980__ $$aI:(DE-Juel1)JCNS-2-20110106 000020180 980__ $$aUNRESTRICTED 000020180 981__ $$aI:(DE-Juel1)JCNS-2-20110106 000020180 981__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000020180 981__ $$aI:(DE-Juel1)JCNS-2-20110106
