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 ...
Energetic evaluation and optimization of hydrogen generation and compression pathways considering PEM water electrolyzers and electrochemical hydrogen compressors

Zachert, Lars; Suermann, Michel; Bensmann, Boris; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2021)

Electrochemical hydrogen compression is seen as a promising alternative to mechanical compression in the context of power-togas plants. It can be carried out either as direct co-compression in a water electrolyzer (WE) or ...
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 ...
