Elucidating the effect of mass transport resistances on hydrogen crossover and cell performance in PEM water electrolyzers by varying the cathode ionomer content

Trinke, P.; Keeley, G.P.; Carmo, M.; Bensmann, B.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing Ltd., 2019)

An important challenge for polymer electrolyte membrane (PEM) water electrolysis is to reduce the permeation of the produced gases. This crossover affects the cell efficiency and causes safety issues. The crossover increases ...
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 ...
Membrane Interlayer with Pt Recombination Particles for Reduction of the Anodic Hydrogen Content in PEM Water Electrolysis

Klose, C.; Trinke, P.; Boehm, T.; Bensmann, B.; Vierrath, S.; Hanke-Rauschenbach, R.; Thiele, S. (Pennington, New Jersey : Electrochemical Society (ECS), 2018)

Polymer electrolyte membrane (PEM) water electrolysis is a key technology for sustainable hydrogen based energy supply. Gas permeation through the PEM leads to hydrogen in oxygen at the anode side posing a safety hazard ...
Temperature and Performance Inhomogeneities in PEM Electrolysis Stacks with Industrial Scale Cells

Krenz, T.; Weiland, O.; Trinke, P.; Helmers, L.; Eckert, C.; Bensmann, B.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing, 2023)

In this work temperature inhomogeneities and their influence on PEMWE performance of industrial-scale stacks are investigated. Three temperature differences are examined: (i) between the inlet and outlet, (ii) in-between ...
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 ...
