%X Water vapour has been deliberately introduced into an oxygen gas electrode in an equimolar NaXO3-KNO3 melt at 300º. When this is done the slope of the line obtained for ECe11 against log[O2-]Total changes from the 2.303RT/2F obtained with dry oxygen to almost exactly 2.303RT/F. On discontinuing the passage of water vapour into the melt, the cell reverts to its original condition within 3 hr. These experimental results are discussed theoretically. The results also yield a value of 3.2 x 10-2 for the equilibrium constant of the reaction    O2 + H2O = 2OH-
