Oikonomidis, Silvestros (author), Ramdin, M. (author), Moultos, O. (author), Bos, Albert (author), Vlugt, T.J.H. (author), Rahbari, A. (author)Due to the intermittency of renewable energy sources, alkaline water electrolyzers are typically operated at partial load compared to the nominal design value. It is well-known that gas crossover is dominant at low current densities leading to higher anodic hydrogen content and higher cathodic oxygen content in the separator tanks. High...journal article 2023

Deshmukh, R.S. (author), Rituraj, G. (author), Vahedi, H (author), Shekhar, A. (author), Bauer, P. (author)Electrolysis requires a high DC current at low voltage to produce hydrogen from water. Designing power converters for such a load requirement could be challenging while fulfilling the galvanic isolation needs. Therefore, prior knowledge of the electrolyzer's impact on the converter operation should be needed. In this context, this paper...conference paper 2023
