Evaluation of the Efficiency of an Elevated Temperature Proton Exchange Membrane Water Electrolysis System

Bonanno, Marco; Müller, Karsten; Bensmann, Boris; Hanke-Rauschenbach, Richard; Peach, Retha; Thiele, Simon (Pennington, NJ : Electrochemical Society, 2021)

In recent years, a significant interest has been growing in elevated temperature (ET) electrolytes for proton exchange membrane water electrolysis (PEMWE). In this study, the energy and exergy analysis developed for PEMWE ...
Hydrogen Crossover in PEM Water Electrolysis at Current Densities up to 10 A cm−2

Martin, Agate; Trinke, Patrick; Bensmann, Boris; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2022)

Hydrogen crossover poses a critical issue in terms of the safe and efficient operation in polymer electrolyte membrane water electrolysis (PEMWE). The impact of key operating parameters such as temperature and pressure on ...
Is iridium demand a potential bottleneck in the realization of large-scale PEM water electrolysis?

Minke, Christine; Suermann, Michel; Bensmann, Boris; Hanke-Rauschenbach, Richard (New York, NY [u.a.] : Elsevier, 2021)

Proton exchange membrane water electrolysis (PEMWE) is a key technology for future sustainable energy systems. Proton exchange membrane (PEM) electrolysis cells use iridium, one of the scarcest elements on earth, as catalyst ...
Modeling Overpotentials Related to Mass Transport through Porous Transport Layers of PEM Water Electrolysis Cells

Schmidt, Gergely; Suermann, Michel; Bensmann, Boris; Hanke-Rauschenbach, Richard; Neuweiler, Insa (Bristol : IOP Publishing Ltd., 2020)

Porous transport layers (PTL) are key components of proton exchange membrane water electrolysis (PEMWE) cells controlling species transport. Further optimization requires better understanding of how PTLs influence ...
Modelling Water Transport Limitations and Ionic Voltage Losses in Bipolar Membrane Water Electrolysis

Weiland, Oskar; Trinke, Patrick; Bensmann, Boris; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2023)

This work analyses the water transport and ionic losses in bipolar membranes at water electrolysis cells conditions. In common bipolar setups, water is split at the bipolar interface between the anion exchange membrane ...
Optimization of anodic porous transport electrodes for proton exchange membrane water electrolyzers

Bühler, Melanie; Hegge, Friedemann; Holzapfel, Peter; Bierling, Markus; Suermann, Míchel.; Vierrath, Severin; Thiele, Simon (Cambridge : Royal Society of Chemistry, 2019)

In this study we investigate the potential of porous transport electrode (PTE) based membrane electrode assemblies (MEAs) for proton exchange membrane water electrolysis. The focus is on the overpotential determining anodic ...
Structural mechanics analysis of fabric-reinforced membranes in proton exchange membrane water electrolysis

Kink, Julian; Ise, Martin; Bensmann, Boris; Junker, Philipp; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2023)

Membranes are a key component of proton exchange membrane water electrolysis (PEMWE) cells and are exposed to various stressors during operation, which can significantly reduce cell lifetime. PEMWE membranes incorporating ...
Understanding electrical under- and overshoots in proton exchange membrane water electrolysis cells

Immerz, C.; Bensmann, B.; Trinke, P.; Suermann, M.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing Ltd., 2019)

Ability of dynamic operation seems to be an important feature of proton exchange membrane water electrolyzers (PEMWE) to become a relevant part of the future energy system. However, only few fundamental analyzes of the ...
