Bleeker, J.J. (author), van Kasteren, Celine (author), van Ommen, J.R. (author), Vermaas, D.A. (author)To make green hydrogen more economically attractive, the energy losses in alkaline electrolysis need to be minimized while operating at high current densities (1 A cm<sup>−2</sup>). At these current densities the ohmic resistance and gas bubbles effects contribute largely to the energy losses. To mitigate the gas bubbles losses, we...journal article 2024
