Abstract
A gas-depolarizable galvanic cell in which restricted gas and water vapor access to the gas-depolarizable cathode is provided by interposing a gas and moisture impermeable barrier in the gas communication path and carefully controlling the size of holes or openings in the barrier so as to restrict the gas flow rate past the barrier.
