description Individual cells (10) in a stack of solid oxide fuel cells are electrically joined to each other by means of intercalated interconnectors (18). Appropriate contact between the interconnector (18) and the electrode (16) required for reliable electrical connection is impeded by irregularities on the surfaces thereof. Said irregularities are smoothed out by an electrical contact layer (42)arranged between the electrode (12, 16) and the interconnector (18) which is made of a composite substance with at least two phases. The first phase consists of glass or glass ceramics. The second phase exhibits electrical conductivity.
