GRUPPO DI TENUTA IMPIEGANTE UNA MEMBRANA MICROPOROSA PER CELLE ELETTROCHIMICHE,E PROCEDIMENTO PER LA FABBRICAZIONE DELLO STESSO

摘要

A self sealing microporous membrane of utility especially in electrochemical cells of the gas-depolarized type comprising a microporous polymer membrane of a density range between about 0.7 and 1.9 grams per centimeter embodies a pressurized sealing zone of maximum density and zero porosity. Such pressurized zone is located to provide a seal against leakage of electrolyte.
