ABSTRACT:
The electrode comprises an internal reference half-cell at stable potential comprising a conductive sheet, e.g. of metal of carbon, covered by a redox system. The redox system comprises a thin dehydrated layer of Prussian blue deposited by contact between the sheet and a mixture of alkaline ferrocyanide and a ferric salt.
