HIGH-TEMPERATURE FUEL CELLS

摘要

The invention relates to a high-temperature fuel cell (2) with a cathode (6) comprising at least one first layer (12) containing 30-60 wt. % of a first electrolyte made of zirconium oxide (ZrO2) and at least an amount of scandium oxide (Sc2O3), thereby providing high ionic conductivity for said cathode (6). Ionic conductivity is substantially preserved independently of operating time (t).
