| 摘要 |
A bipolar diaphragm electrolyzer particularly suitable for electrolysis of alkali metal halide aqueous solutions wherein the bipolar wall separating the electrode compartments is formed of at least two sheets made of different metals, suitable pressure being applied against the metal sheets to provide for electrical continuity across the bipolar wall, said pressure being exerted either by means of resilient elements which are compressed when the electrolyzer is closed or by maintaining the electrode compartments under a sufficient hydrostatic pressure during the electrolytic process.
