title: [Experimental research on the process of decomposition of a CO2-CO-H2O-H2-N2 gas mixture in an electrolytic cell with a solid electrolyte].
abstract: The experimental investigation was carried out in an electrolytic cell having the form of a short tube and containing a solid electrolyte of the following composition 0.9 ZrO2-0.1 Y2O3. The concentration of the gaseous mixtures investigated [H/C]00 varied in the range 0.22 to 18.0. The cathode polarization of the cell with platinum electrodes was measured as a function of the composition of the gaseous mixture [H/C]00 and oxygen content [O/C + H]0 at the temperatures 800, 900 and 1000 degrees C. The measurements demonstrated that the cell cathode polarization decreased as the water concentration in the starting mixture increased. The dependence of the cell cathode polarization on the oxygen content had minima in a specific range of the values [O/C + H]0. The minimal narrowed and shifted towards lower rations of [O/C + H]0. Simultaneously, the cell cathode polarization decreased as the water content in the starting gaseous mixture increased (ratio of [H/C]00).
