ResumoA method for preparing low resistance bipolar membranes is described. The membranes are prepared by pressing together manually, separate anion and cation exchange membranes which have been pretreated by immersion in an alkaline solution of a metallic salt. The operating voltage for the bipolar membrane is about 1.0 V, when it separates 1 molar acid and alkali solutions and the current is 100 mA-cm−2. The current efficiency for water splitting is close to 100%. The electrical characteristics are stable under a continuous applied current, for over a year.
