A SOLID ELECTROLYTE CARBON DIOXIDE REDUCTION SYSTEM.
Abstract
Solid electrolyte cells utilizing a 90 mole percent Zr02(-10) mole percent Y203 electrolyte and platinum electrodes were used for the reduction of carbon dioxide to carbon monoxide and oxygen. Methods of fabricating multicell units were investigated and the performance of these units under a variety of temperature conditions and feed gas compositions was studied. Current efficiencies of these units were found to vary with temperature and current density when pure carbon dioxide was used as a feed. Multicell units were operated continuously for up to 750 hours with no evidence of cell deterioration. Studies on single-cell units were carried out to correlate cell polarization effects with feed gas composition, voltage and current density at a fixed temperature. (Author)
