Pure Water—Solid Polymer Electrolyte Systems

Conductivity in Pure Water—Solid Polymer Electrolyte Systems 

In SPE cells, electrocatalyst particles are bonded to the membrane surfaces. It is important to mention that good bonding

The solid polymer electrolyte cells are viewed as being particularly appropriate for the treatment of high purity water systems, including the provision of ultra pure water for the pharmaceutical industry, cf. Ref. [205], The process is often coupled with UV radiation which serves to decompose unwanted, residual ozone [133],... 

Generally, lead dioxide (Pb02) and platinum (Pt) electrodes are used as electrocatalysts for ozone generation [2-4]. The electrolytic cell consists of a porous anode, a porous cathode and a solid-state polymer electrolyte membrane instead of an electrolyte solution these are stacked, as shown schematically in Fig. 24.1(a). Pure water, or tap water without additives as an electrolyte, is directly supplied to the anode compartment, the electrolysis of water occurs, and the electrolyzed water containing dissolved ozone is directly drained. Electrolytic ozonizers based on this system have already become available on the market.
