ABSTRACT:
This disclosure is directed to a shutdown procedure for use in gas electrodes, e.g., oxygen (air) cathodes, which comprises imposing a nitrogen purge on the cell containing said electrode upon power shutdown and maintaining this nitrogen atmosphere (blanket) during the period of the shutdown. It has been discovered that the use of this procedure enables maintaining of the low voltage operation achieved prior to power shutdown upon restart of the cell when the power has been restored.
