An expression for the concentration impedance (CI) taking into account oxygen transport in the cathode catalyst layer (CCL) and the gas diffusion layer (GDL) is derived. In the static limit the CI gives the limiting current density due to oxygen transport in the GDL. The Bode plots of real and imaginary part of the CI have minima at the characteristic frequencies corresponding to oxygen transport in the GDL and the CCL, respectively. These features enable direct estimation of the respective oxygen diffusion coefficients without curve fitting. 000873875 536__ $$0G:(DE-HGF)POF3-135$$a135 - Fuel Cells (POF3-135)$$cPOF3-135$$fPOF III$$x0 000873875 588__ $$aDataset connected to CrossRef 000873875 773__ $$0PERI:(DE-600)2981331-1$$a10.1016/j.etran.2019.100026$$gVol. 2, p. 100026 -$$p100026 -$$teTransportation$$v2$$x2590-1168$$y2019 000873875 8564_ $$uhttps://juser.fz-juelich.de/record/873875/files/1-s2.0-S2590116819300268-main.pdf$$yRestricted 000873875 8564_ $$uhttps://juser.fz-juelich.de/record/873875/files/1-s2.0-S2590116819300268-main.pdf?subformat=pdfa$$xpdfa$$yRestricted 000873875 909CO $$ooai:juser.fz-juelich.de:873875$$pVDB 000873875 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129878$$aForschungszentrum Jülich$$b0$$kFZJ 000873875 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 000873875 9141_ $$y2020 000873875 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000873875 920__ $$lyes 000873875 9201_ $$0I:(DE-Juel1)IEK-14-20191129$$kIEK-14$$lElektrochemische Verfahrenstechnik$$x0 000873875 9201_ $$0I:(DE-Juel1)IEK-3-20101013$$kIEK-3$$lTechnoökonomische Systemanalyse$$x1 000873875 980__ $$ajournal 000873875 980__ $$aVDB 000873875 980__ $$aI:(DE-Juel1)IEK-14-20191129 000873875 980__ $$aI:(DE-Juel1)IEK-3-20101013 000873875 980__ $$aUNRESTRICTED 000873875 981__ $$aI:(DE-Juel1)IET-4-20191129 000873875 981__ $$aI:(DE-Juel1)ICE-2-20101013 000873875 981__ $$aI:(DE-Juel1)IET-4-20191129
