INTERCONNECTOR FOR A HIGH-TEMPERATURE SOLID ELECTROLYTE FUEL CELL

摘要

The invention describes an interconnector for a high-temperature solid electrolyte fuel cell composed of a sintered chromium alloy which has sintering pores and contains > 90% by weight of Cr, from 3 to 8% by weight of Fe and optionally from 0.001 to 2% by weight of at least one element of the group of rare earth metals; where the chromium alloy contains from 0.1 to 2% by weight of Al and the sintering pores are at least partially filled with an oxidic compound containing Al and Cr. The interconnector has a high impermeability to gas and dimensional stability.
