2111689 9300459 PCTABS00019 The invention relates to an electrolytic cell and a capillary slit electrode for gas-developing or gas-consuming electrolytic processes and reactions, and an electrolysis process therefor. According to the invention, the capillary slit electrode (2, 3) has conduits (10, 13, 11, 11') enabling the separate flow of reaction gas and electrolyte/permeate in the electrode. The electrode is preferably hydrophilic in a narrow internal region (10, 13) for mounting on a separator, while elsewhere (11, 11') it is hydrophobic. Thus electrolyte/permeate penetrates only into the region of the capillary slit electrode near the separator, while the region away from the separator remains free of electrolyte/permeate, so facilitating the unimpeded flow of the reaction gas. The invention is applicable especially in electrolytic cells for chlor-alkali or hydrogen electrolysis, and in the construction of cells for the generation of electric power.
