Abstract
The present invention relates to a retrofitted electrolytic cell and a method for retrofitting an electrolytic cell comprising an anode and a cathode compartment, a separator partitioning the compartments, said cathode compartment comprising a hydrogen evolving cathode. The method comprises making at least one substantially horizontal slit in the hydrogen evolving cathode resulting in plural cathode members, bending the edge of at least one cathode member at the slit away from the separator, arranging a gas diffusion electrode to the cathode members on the side facing the separator, and arranging an electrolyte layer to the gas diffusion electrode. The invention also relates to the use of a retrofitted electrolytic cell.
