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 ...
Local Current Density and Electrochemical Impedance Measurements within 50 cm Single-Channel PEM Electrolysis Cell

Immerz, C.; Bensmann, B.; Trinke, P.; Suermann, M.; Hanke-Rauschenbach, R. (Pennington : Electrochemical Society (ECS), 2018)

The present analysis shows the local distribution of current density and EIS measurements along a 50 cm single-channel proton exchange membrane water electrolysis (PEMWE) cell. Measurements for operating modes with one ...
Resource-Efficient Gigawatt Water Electrolysis in Germany—A Circular Economy Potential Analysis

Matz, Levin; Bensmann, Boris; Hanke-Rauschenbach, Richard; Minke, Christine ([Cham] : Springer International Publishing, 2024)

Green hydrogen will play a key role in the future energy system. For the production of green hydrogen, an installation of alkaline (AWE) and proton exchange membrane water electrolysis (PEMWE) of several gigawatts per year ...
