Abstract The behaviour of cells of the form Ag(s) |Ag7I4AsO4(s)|M(s), where Ag7I4AsO4 is a vitreous solid electrolyte with high silver ion conductivity and M is an inert anode such as platinum or stainless steel, has been investigated under different levels of d.c. polarisation. It has been shown that electrolytes of this type are not readily electrolysed, even under applications of large fields (despite the negligible impedance of the cathode). On the other hand, the anode is readily depolarised by water vapour, and the resulting cell current is related to the humidity of the gas in contact with it. The applicability of such cells for quantitative humidity determination by amperometry has been assessed.
