An actuator element comprises an ion exchange membrane and a pair of electrodes attached to opposite surfaces of the ion exchange membrane; the ion exchange membrane in a water-containing state being caused to bend and/or deform by application of an electric potential difference thereacross.

Actuator element

A positive electrode suitable for the electrolysis of water is produced by immersing a nickel electrode in an aqueous solution containing a nickel salt, a rhodium salt, and an alkyl amine borane.

Method for production of positive electrode for electrolysis of water

A chemical-resistant diaphragm composed of a fluorine-containing polymer and potassium titanate and a method for the manufacture of said diaphragm by the steps of adding titanium oxide or titanic acid to a fluorine-containing polymer and heating the resultant mixture in the presence of potassium hydroxide.

Method of making a chemical-resistant diaphragm thereof

Removal of silver and reduction of COD value in used or exhausted photographic fixing solution are effectively conducted by electrolysis of reversing repeatedly polarity of positive and negative electrodes.
