Testing of operating commercially manufactured cells under conditions of high temperature and low PO2 atmospheres revealed two anomalies. First, there was a sudden EMFsignal loss above 1200°C. Second was the increase in EMF between 950° and 1200°C when tested in an atmosphere of CO + CO2 with volumetric mixing ratio of 1:1. Future work will focus on identifying the source of the anomalies and solutions which will allow their use of the cells under the desired operating conditions.
