Small pores are for the electro chemical reactions while large ones are for flow paths of reactants. Potentiometric sensors make use of thermodynamic equilibration between the gas and the solid. Some porous electrodes require two mode distributions of pore sizes.

Coorstek center for advanced materials. Chemical sensors are measurement devices that convert a chemical or physical property of a specific analyte into a measurable signal whose magnitude is normally proportional to the concentration of the analyte. Chemical sensing principles methods and applications. Electrostatic potential drops across interfaces caused by the exchange of ions together with electrons may be used in various ways to measure the concentration of chemical species.

Many electrodes used in electro chemical devices including gas purifiers gas sensors fuel cells and chemical analyzers are porous ceramics.
