In-situ Diagnostics in Water Electrolysers
Workshop „Diagnostics in Electrolysis“
A workshop dedicated to the topic of diagnostics was held in Kopenhagen on 16th June 2017
Programme:
Vince Beyer (Greenlight Innovation): Electrolyser testing – state of the art and outlook
Philipp Lettenmeier (DLR): Degradation and applied impedance spectroscopy
Piotr Jasinski (Technical University of Gdansk): Analysis of impedance spectra - Distribution of
Relaxation times
Marie Lund Traulsen (Technical University of Denmark): t In-operando Raman Spectroscopy
Indro Biswas (DLR): Monitoring of current density distribution
Vesa Ruuskanen (University of Lappeenranta): Electrolyser control strategies
Near operando atomic force microscopy on PEMWE electrodes
Fluid cell measurements of membranes, electrodes or half-MEAs can give insight into the structure and
current distribution under operational conditions. Evolution of gas nanobubbles reveals
eactivity/permeability
5.5 kW PEMWE system delivered
An industrial scale PEM based water electrolyser was
delivered. The Elze E1050 system by EWII A/S of Denmark
uses power of 5.5, can produce 1 normal m³/h, and can be
used for the development of an industrial scale diagnostics
tool, now.
Segmented cell technology demonstrated in PEMWE
The used technology for locally resolved current density measurement could be proven for proton
exchange membrane based electrolysis. Scenarios/situations evaluated for their specific patterns are
reversible deactivation by water starvation (see image), irreversible deactivation by poisoning of the
catalyst, the local evaluation of different flow channel layouts, and the application during cell assembly.
Near-ambient-pressure XPS in electrochemical cell
In PEMWE electrode samples, investigated with Synchrotron based x-ray photoelectron spectroscopy
under near ambient pressure conditions (NAP-XPS), the degradation mechanism of the IrRu catalyst
was studied during electrolysis operation, allowing to unveil the stabilisation mechanism.
Amendment approved by FCH JU
The transition of the AEMWE activities in the project was approved by the European Fuel Cells and
Hydrogen Joint Undertaking. The overall plan remains unchanged. The second part in this amendment
is a cost-neutral extension by 12 months.
1st prototype ready
The prototype of the segmented printed circuit for for locally resolved curent density measurements in
Anion Exchange membrane bases water electrolysis (AEMWE) was designed, manufactured, and
delivered to Heliocentris Italy.
Heliocentris Italy replace Acta
Heliocentris AG have acquired Acta S.p.A. The new company Heliocentris Italy S.r.l., a 100% daughter
company of Heliocentris AG, is going to continue the AEMWE activities in the INSIDE consortium.
