(DE19705874-A1)      A SOFC fuel cell stack current collector has a base (2) of an alloy containing more than 2.0 wt.% aluminium and one or more contact elements (3) of an alloy containing less than 2.0 wt.% aluminium.    Preferably, both alloys are heat resistant ferritic alloys.    Also claimed is a fuel cell stack including the above current collector (1) in electrically conductive connection with a fuel cell electrode (4) by means of the contact elements (3).    USE -   In a fuel cell stack (claimed), especially a SOFC stack.    ADVANTAGE -   Chromium oxide evaporation is suppressed by the relatively high aluminium content in the base alloy (e.g. Cr5FeY2O3) which causes preferential formation of a stable aluminium oxide layer. Satisfactory electrical conductivity at the contact points between the current collector and the electrode is ensured by the relatively low aluminium content in the contact elements which allows formation of a more conductive chromium oxide layer.
