Electro-chemical sensor

摘要: Electro-chemical sensor to determine oxygen concentration in hot internal combustion exhaust gases the form of a closed, tubular element having solid ion conductive electrolyte; an electron-conductive coating on inner surface thereof; porous or fissured electron layer outer said electrolyte part surface, pores fissures being macroporous, material which catalyzes formation from those compounds that are thermodynamically stable at temperature; and protective electrically insulating layer. Preferably, top heat-resistant metal is applied, has additionally properties act as getter with respect poisons affecting catalyzing material.
