Abstract
A membrane assembly, useful as a membrane in electrodialytic and electrolytic cells, is made by holding together a plurality of thin layers of membrane material under pressure and with boundary layers of liquid covering their major surfaces. Such membrane assemblies allow the passage therethrough of ions when an electric potential difference is impressed across the membrane assembly but effectively bar the passage of water and gases. They also bar or limit ionic and salt mass transfer in the absence of such a potential difference (during non-use of the cell). They make excellent long lasting cell components, capable of being manufactured simply and economically from any of a variety of membrane materials to produce membranes of desired properties.
