Characterisation tools development for PEM electrolysers
Van der Merwe, Jan; Uren, Kenny; Van Schoor, George; Bessarabov, Dmitri (Elsevier, 2014)Electrochemical impedance spectroscopy (EIS), current interrupt (CI) and current mapping (CM) were investigated as in-situ characterisation tools for PEM electrolysers. A 25 cm2 cell with titanium anode and carbon cathode ... -
Evaluation of MEA manufacturing parameters using EIS for SO2 electrolysis
Krüger, Andries J.; Krieg, Henning M.; Van der Merwe, Jan; Bessarabov, Dmitri (Elsevier, 2014)Membrane electrode assembly (MEA) manufacturing parameters such as hot pressing pressure and pressing time were investigated for the use in a SO2 electrolyser. The SO2 electrolysis was optimised in terms of cell temperature, ... -
A study of the loss characteristics of a single cell PEM electrolyser for pure hydrogen production
Van der Merwe, Jan; Uren, Kenny; Bessarabov, Dmitri (IEEE, 2013)In this paper the losses of a proton exchange membrane (PEM) single cell electrolyser were investigated. The ohmic, activation and mass transfer losses are the most prominent losses in a PEM electrolyser. The Electrochemical ...
