High-temperature, low-temperature—gradient methods for (CO-)electrolysis of water (SOEC) or for producing electricity within a reactor or fuel-cell stack (SOFC) respectively

摘要

The invention essentially consists in supplying fuel (either steam or a mixture of steam with CO2 or H2 or CH4) to distinct zones of a cell or a group of stacked cells and of an adjacent cell or group of adjacent stacked cells within a given (co-)electrolysis reactor or a SOFC fuel-cell stack.
