| 摘要 |
The invention concerns an air depolarization cell or battery. The positive electrode is supplied with air through at least one cavity formed by at least two funnels formed directly by molding or otherwise in the mass of the positive electrode separated by a portion of the mass of the positive electrode, each funnel communicating with the outside air at one of their ends and communicating together by a passageway similarly formed directly in the mass of the positive electrode at the level of their other ends. The ratio between the area of the surface of each funnel through which air flows into the electrode and the volume of air therein is different for the two funnels. |
