Abstract

PURPOSE:To manufacture an stable electrode covered with partition film with little change on standing simply and cheaply by forming a film of precious metals having pin-holes on the external surface of a porous cylindrical body. CONSTITUTION:On the external surface of cylindrical body 1 having the bottom 2 and formed of porous ceramics or of porous plastics a film of precious metal such as platinum is formed by means of spattering or evaporation and the surface thereof is treated into the shape, wherein a plenty of pin-holes with a diameter of about 0.1-1.0mu are produced, for forming a cathode of electrode covered with a partition film. The inside of cylindrical body 1 is filled with particles 5 of lead or cadmium constituting an anode while being filled with the electrolyte 6 such as the solution of potassium carbonate. Further the external side of the cylindrical body 1 is covered with the partition film 13 for transmitting gas such as silicon rubber. Said cathode is connected with the lead wire 12 and the anode is connected with the lead wire 11 through a lead rod 10. Thereby the electrode with little change on standing and a long life can be simple manufactured.
