N-Methyltaurine and trifluoromethanesulfonic acid (TfOH) were mixed at various stoichiometric ratios in order to investigate the influence of an acid or base excess. The proton conductivity and self-diffusion of the “neat” and with 6 wt% water samples were investigated by following electrochemical and NMR methods. The composition change in the complete species and the relative proton transport mechanism based on the NMR results are discussed in detail. During fuel cell operation, the presence of significant amounts of residual water is unavoidable. In PEFC electrolytes, the predominating proton transfer process depends on the cooperative mechanism, when PILs are fixed on the polymer matrix within the membrane. Due to the comparable acidity of the cation [2-Sema]+ and the hydroxonium cation, with excess N-methyltaurine or H2O in the compositions, fast proton exchange reactions between the protonated [2-Sema]+ cation, N-methyltaurine and H2O can be envisaged. Thus, an increasing ratio of cooperative proton transport could be observed. Therefore, for polymer membrane fuel cells operating at elevated temperatures, the highly acidic PILs with excess bases are promising candidates for future use as electrolytes. 000887945 536__ $$0G:(DE-HGF)POF3-135$$a135 - Fuel Cells (POF3-135)$$cPOF3-135$$fPOF III$$x0 000887945 588__ $$aDataset connected to CrossRef 000887945 7001_ $$0P:(DE-Juel1)140525$$aKorte, Carsten$$b1$$eCorresponding author 000887945 773__ $$0PERI:(DE-600)2623224-8$$a10.1039/D0RA08969A$$gVol. 10, no. 69, p. 42596 - 42604$$n69$$p42596 - 42604$$tRSC Advances$$v10$$x2046-2069$$y2020 000887945 8564_ $$uhttps://juser.fz-juelich.de/record/887945/files/Invoice_INV_007748.pdf 000887945 8564_ $$uhttps://juser.fz-juelich.de/record/887945/files/d0ra08969a.pdf$$yOpenAccess 000887945 8767_ $$8INV_007748$$92020-11-17$$d2020-11-20$$eAPC$$jZahlung erfolgt$$zGBP 750 / Belegnr. 1200159874 000887945 909CO $$ooai:juser.fz-juelich.de:887945$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000887945 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)173951$$aForschungszentrum Jülich$$b0$$kFZJ 000887945 9101_ $$0I:(DE-588b)36225-6$$6P:(DE-Juel1)173951$$aRWTH Aachen$$b0$$kRWTH 000887945 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)140525$$aForschungszentrum Jülich$$b1$$kFZJ 000887945 9101_ $$0I:(DE-588b)36225-6$$6P:(DE-Juel1)140525$$aRWTH Aachen$$b1$$kRWTH 000887945 9131_ $$0G:(DE-HGF)POF3-135$$1G:(DE-HGF)POF3-130$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lSpeicher und vernetzte Infrastrukturen$$vFuel Cells$$x0 000887945 9141_ $$y2020 000887945 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000887945 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bRSC ADV : 2018$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000887945 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium$$d2020-09-05$$wger 000887945 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2020-09-05 000887945 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2020-09-05 000887945 920__ $$lyes 000887945 9201_ $$0I:(DE-Juel1)IEK-14-20191129$$kIEK-14$$lElektrochemische Verfahrenstechnik$$x0 000887945 9801_ $$aAPC 000887945 9801_ $$aFullTexts 000887945 980__ $$ajournal 000887945 980__ $$aVDB 000887945 980__ $$aUNRESTRICTED 000887945 980__ $$aI:(DE-Juel1)IEK-14-20191129 000887945 980__ $$aAPC 000887945 981__ $$aI:(DE-Juel1)IET-4-20191129
