Communication - Proving the Importance of Pt-Interlayer Position in PEMWE Membranes for the Effective Reduction of the Anodic Hydrogen Content

Martin, Agate; Abbas, Dunia; Trinke, Patrick; Böhm, Thomas; Bierling, Markus; Bensmann, Boris; Thiele, Simon; Hanke-Rauschenbach, Richard (Pennington, NJ : Electrochemical Society, 2021)

Gas crossover through the membrane poses a significant challenge to proton exchange membrane water electrolysers. This work investigates the influence of the position of platinum-based recombination interlayers integrated ...
Degradation of proton exchange membrane (PEM) water electrolysis cells: Looking beyond the cell voltage increase

Suermann, Michel; Bensmann, Boris; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing Ltd., 2019)

The degradation of proton exchange membrane water electrolysis cells is usually measured in a temporal increase of the cell voltage. Although this is sufficient to evaluate the stability of a system, it is less suitable ...
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 ...
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 ...
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 ...
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 ...
