A molten carbonate fuel cell is constructed of plural stacked individual cell units, that each respectively include a porous, electrolyte saturated matrix (3) sandwiched between a cathode (2) and an anode (4), and current collectors (5, 6) respectively arranged between the anode (4) and a first separator plate (7), and between the cathode (2) and a second separator plate (8). Especially the cathode current collector (6) includes a stainless steel core (16) that is coated on at least one surface with an aluminum-containing layer (14). Preferably both surfaces of the stainless steel core (16) are coated with aluminum-containing layers (14A, 14B), except for a contact area (12) at which the stainless steel core (16) directly contacts the cathode (2). The aluminum-containing layer (14) prevents or minimizes the occurrence of an oxidation reaction that would otherwise lead to significant loss of the electrolyte.
