Synthetic resin membrane for electrolytic purposes - with pores filled by titanium hydroxide, zirconium hydroxide, zirconium silicate or silica gel

摘要

Diaphram membrane for use in fuel cells or for brine electrolysis is formed of a synthetic resin with pores filled by titanium hydrosale, zirconium hydrosade, zirconium silicate, or silica gel, and has a specific electric conductivity of 1 x 10-3 - 10-1 mho/cm, and a specific permeability to water of 10-3 -150 l/m2 hr, at a pressure difference of 0.5 kg/cm2. Combines low electric resistance with low water permeability.
