At the sensing end of the cell is a diffusion membrane, whose thickness is very accurately controlled. Near the diffusion membrane lies the oxygen sensing
The anode structure is larger than the cathode. It is made of lead and is designed to maximize the amount of metal available for chemical reaction.
