摘要：
A NOx gas detecting apparatus including an oxygen pumping cell for removing oxygen from a measurement gas, and a NOx detecting cell positioned downstream from the oxygen pumping cell to detect concentration of NOx in the measurement gas, the NOx detecting cell being configured to measure current which flows when oxygen generated from reducing NOx is pumped, wherein the NOx detecting cell has a NOx detecting cathode made of an electrode material including at least one alloy selected from the group consisting of a Pt-Pd alloy, a Pt-Au-Pd alloy, and a Pt-Pd-Rh alloy.
