| Abstract: |
The interconnector (1) for high temperature fuel cells is arranged between a first and a second planar electrochemically active element (2, 2'). In this it separates a chamber (41) containing a combustion gas from a chamber (51, 53) containing oxygen. A porous sinter body (10) of the interconnector has pores (101) which are at least partly sealed by a medium (11'). Through the sealing, a passage of gases between the named chambers (41, 51) is prevented.
