Abstract
In an apparatus for producing acidic electrolyzed water, the use of a protection membrane having slits or other discontinuities allows the protection of a permeable membrane, such as an anion-permeable or anion-selective membrane, from chlorine generated by the electrolysis. The protection membrane further preserves the electrical conductivity of the membrane and electrode assembly, because of a venting action of trapped gas and fluid through the slits. The protection membrane is useful both in three chambered electrolyzers and in two chambered electrolyzers. The preferred protection membrane has slits formed by overlapping strips of fabric or the like. The preferred fabric is a non-woven fabric.
