High-temperature fuel-cell battery
Abstract
Abstract A HIGH-TEMPERATURE FUEL-CELL BATTERY CONSISTS OF A COLUMN OF FUEL CELLS CONNECTED ELECTRICALLY IN SERIES, AND EACH CELL IS COMPOSED OF A PLURALITY OF SUPERIMPOSED LAYERS CONSISTING OF A POROUS ELECTRON-CONDUCTING LAYER THROUGH WHICH FUEL GAS IS FED TRANSVERSELY, A GAS-TIGHT OXYGEN-ION-CONDUCTING LAYER OF CUBICALLY STABILIZED ZIRCONIUM OXIDE SUCH AS ZRO2 WITH AN ADDITIVE OF Y2O3 FORMING THE ELECTROLYTE, AND A POROUS ELECTRON-CONDUCTING LAYER SUCH AS MN2O3 THROUGH WHICH AN OXIDANT GAS IS PASSED TRANSVERSELY. A GAS-LIGHT ELECTRON-CONDUCTING LAYER SEPARATED EACH CELL FROM AN ADJACENT CELL IN THE COLUMN, A SIMILAR GAS-TIGHT ELECTRON-CONDUCTING LAYER IS PROVIDED AT THE UPPER AND LOWER ENDS OF THE COLUMN AND ALL OF THE LAYERS OF THE FUEL CELLS AND THE SEPARATION LAYERS BETWEEN ADJACENT CELLS ARE SINTERED TOGETHER TO ESTABLISH A COMPACT COLUMNAR STRUCTURE.
