Solid Oxide Electrochemical Cells for Nitrogen and Oxygen Production
Abstract
This work presents an efficient electrochemical process for N<sub>2 </sub>and O<sub>2</sub> production based on a solid oxide electrochemical cell technology by oxygen extraction from air. Cells with a 53×53 mm<sup>2 </sup>size consist of ca.10 μm CGO electrolyte sandwiched between composite electrodes made from either LSCF-CGO, or LSF-CGO were produced by a conventional tape casting method. To boost performance at low temperature, the electrodes were infiltrated with Pr-oxide. The electrochemical performance of the cells were characterized by iV and EIS at different temperatures with air used as feed stock to the cathode compartment and air, or oxygen used as sweep gas to the anode compartment. A voltage below 200mV is achieved to drive a current of 1A/cm<sup>2</sup> through the cell, which can provide a purity of 90% of N<sub>2 </sub>at 650 °C. The cells were demonstrated to operate for producing a >98% pure N<sub>2</sub> stream without degradation over a 1500h period at cell voltages below 255mV.
