    • 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 ...
    • Development and testing of an anion exchange membrane electrolyser 

      Manolova, Mila; Kerres, Jochen; Schoeberl, Claudia; Freudenberger, Renate; Ellwein, Corina (Elsevier, 2015)
      In the context of energy policy and the use of renewable energies, our research institute collaborates with other partners on the development of a compact, environmental-friendly and effective electrolyser for efficient ...
    • The effect of a ripple wave power supply on PEM electrolysis efficiency 

      Buitendach, H.P.C. (North-West University (South Africa), 2021)
      The two matured water electrolysis technologies commercially available today are Alkaline water electrolysis and Proton exchange membrane water electrolysis (PEMWE). Although alkaline water electrolysis is in a more mature ...
    • SO2 - an indirect source of energy 

      Kriek, R.J.; Van Ravenswaay, J.P.; Potgieter, M.; Calitz, A.; Lates, V. (SAIMM, 2013)
      Global sulphur dioxide (SO ) emissions peaked around the mid- 1970s, after which they declined. However, with the growth of specifically China, emissions are on the rise again. In 2008, global anthropogenic SO emissions ...
    • 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 ...
