Abstract
Disclosed herein is a halogen cell of which a positive electrode and/or a negative electrode is a gas permeable electrode. The gas permeable electrode preferably comprises a hydrophilic layer and a gas permeable layer. Since, in this halogen cell, the decrease of the electrode surface area can be prevented, and the desired gas can be rapidly supplied to the electrode, the quantity of charge is increased and the charging time is reduced. Also disclosed herein is a halogen cell of which a positive electrode and/or negative electrode comprises finely divided hydrophilic portions and hydrophobic portions. In this halogen cell, the quantity of charge and the charging time are also improved.
