A special steel current collector (6), for the cathode of a molten carbonate fuel cell stack, has an aluminium or aluminium alloy coating (14) on one or both sides. Preferably, the coating (14) at the cathode-facing side is absent from the contact areas (12) with the cathode (2). The special steel preferably contains 5-16 wt.% CR, 3-12 wt.% Co and NOTGREATER 0.2 wt.% Al, Y, Ti and/or Ce. Also claimed is production of the above current collector by aluminium or aluminium alloy coating of one or both sides of a perforated special steel sheet which has been bent to form gas supply spaces. |
