摘要
The Nernstian behavior of zirconia oxygen sensors incorporating composite electrodes has been described in the low temperature ( less than 600 degree C) range. The composite electrodes consisting of a semi-conducting metal oxide and platinum lower the operating temperature of oxygen sensors to about 300-350 degree C, well below that achievable with conventional metal or metal oxide electrodes. Complex impedance measurements made as a function of Pt/metal oxide ratio show that both the electrode resistance and the time constant go through a minimum when plotted against Pt content in the composite.
