The performance of Proton Exchange Membrane Electrolytic Cells (PEMECs) is strongly influenced by the conditioning of the Membrane Electrode Assembly (MEA), which serves as a critical step in preparing the MEA for optimal functionality. The conditioning process includes two steps. The pre-treatment, which involves hydrating and chemically or thermally activating the MEA, followed by a break-in procedure that stabilizes the electrochemical performance during initial operation.The conditioning strategies explored in this study include ex-situ and in-situ hydration, acidic treatment, and elevated temperature conditions during the pre-treatment step. The impact of pre-treatment conditions; mechanical, chemical, and thermal on the short-term electrochemical performance of Nafion™ N115-based MEAs highlight the importance of both the pre-treatment and break-in procedures in establishing consistent cell operation.The results show that in-situ pre-treatment allows the membrane to swell under constrained conditions post-assembly, significantly enhances the contact area between the MEA and the porous transport layers, reducing contact resistance and improving overall PEMEC performance. Moreover, acidic treatment and elevated temperature conditions further contribute to improved proton conductivity, leading to reduced Ohmic resistance and cell voltage.While the break-in procedure stabilizes the cell’s electrochemical performance in the short term, further investigation is conducted to evaluate how these conditioning protocols impact the long-term degradation mechanisms. This study presents preliminary findings on the durability of conditioned MEAs under continuous operation and explores how optimizing the conditioning process could contribute to enhanced long-term performance, paving the way for more reliable and efficient PEMEC systems in industrial applications. 001051653 536__ $$0G:(DE-HGF)POF4-1231$$a1231 - Electrochemistry for Hydrogen (POF4-123)$$cPOF4-123$$fPOF IV$$x0 001051653 536__ $$0G:(DE-Juel1)HITEC-20170406$$aHITEC - Helmholtz Interdisciplinary Doctoral Training in Energy and Climate Research (HITEC) (HITEC-20170406)$$cHITEC-20170406$$x1 001051653 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001051653 7001_ $$0P:(DE-Juel1)196699$$aJaved, Ali$$b1 001051653 7001_ $$0P:(DE-Juel1)190785$$aTreutlein, Leander$$b2 001051653 7001_ $$0P:(DE-Juel1)157700$$aKungl, Hans$$b3 001051653 7001_ $$0P:(DE-Juel1)161579$$aJodat, Eva$$b4 001051653 7001_ $$0P:(DE-Juel1)191359$$aKarl, André$$b5 001051653 7001_ $$0P:(DE-Juel1)156123$$aEichel, Rüdiger-A.$$b6$$ufzj 001051653 773__ $$0PERI:(DE-600)2438749-6$$a10.1149/MA2025-01381941mtgabs$$gVol. MA2025-01, no. 38, p. 1941 - 1941$$x2151-2043$$y2025 001051653 8564_ $$uhttps://iopscience.iop.org/article/10.1149/MA2025-01381941mtgabs/meta 001051653 8564_ $$uhttps://juser.fz-juelich.de/record/1051653/files/247th_ECS_Meeting_Niklas_Wolf_V3.pdf$$yOpenAccess 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)190997$$aForschungszentrum Jülich$$b0$$kFZJ 001051653 9101_ $$0I:(DE-588b)36225-6$$6P:(DE-Juel1)190997$$aRWTH Aachen$$b0$$kRWTH 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)196699$$aForschungszentrum Jülich$$b1$$kFZJ 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)190785$$aForschungszentrum Jülich$$b2$$kFZJ 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)157700$$aForschungszentrum Jülich$$b3$$kFZJ 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)161579$$aForschungszentrum Jülich$$b4$$kFZJ 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)191359$$aForschungszentrum Jülich$$b5$$kFZJ 001051653 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)156123$$aForschungszentrum Jülich$$b6$$kFZJ 001051653 9101_ $$0I:(DE-588b)36225-6$$6P:(DE-Juel1)156123$$aRWTH Aachen$$b6$$kRWTH 001051653 9131_ $$0G:(DE-HGF)POF4-123$$1G:(DE-HGF)POF4-120$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1231$$aDE-HGF$$bForschungsbereich Energie$$lMaterialien und Technologien für die Energiewende (MTET)$$vChemische Energieträger$$x0 001051653 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001051653 920__ $$lyes 001051653 9201_ $$0I:(DE-Juel1)IET-1-20110218$$kIET-1$$lGrundlagen der Elektrochemie$$x0 001051653 980__ $$aconf 001051653 980__ $$aVDB 001051653 980__ $$aUNRESTRICTED 001051653 980__ $$aI:(DE-Juel1)IET-1-20110218 001051653 9801_ $$aFullTexts
