DeNora Permelec S.p.A. has developed an electrolyzer (trade name Hydrina) with such an anode [104,105]. The first application has been the production of NaOH from Na2C03. The cell has three compartments, separated by a cation-exchange membrane on the cathode side and a porous diaphragm on the anode side (Fig. 15.19). The hydrogen generated at the cathode goes to the depolarized anode. Water is fed to the cathode...
