  • Bipolar electrolytic cell
    Patent number: 5372692
    Abstract: A bipolar electrolytic cell includes an anode-side partition having protrusions on the anode side which are electrically connected to the anode through conductive members, or recesses formed by causing the anode-side partition to protrude on the cathode side.Use of this bipolar electrolytic cell enables the conductor resistance on the anode side to be small, allows the anode to be easily replaced when its activity as a catalyst has been deteriorated, and makes it possible to effect easy and economic repairs even when trouble has occurred during operation.
