ABSTRACT:
The electrode assembly of a galvanic cell for detecting and measuring small amounts of oxygen absorbed by the assembly is a symmetrical sandwich mounted on an anode plate or blade and including contiguous with the blade on each side thereof a porous anode carrying an anode material such as cadmium covered with a sheet of non-reticulated, porous, non-conductive, electrolyte retentive material wrapped around the blade, a cathode conductor strip wrapped around the sheet of electrolyte retentive material, a sheet of porous cathode material, such as graphite cloth wrapped around that and secured in place and the assembly is immersed in electrolyte, electrically charged and sealed inside an oxygen-free envelope.
