Abstract
A fuel cell, in particular a molten carbonate fuel cell and a method for production thereof are disclosed. The anode (1) and the cathode (2) are each provided on current collectors (4a, 4b), which electrically contact with the relevant electrode (1, 2) and form gas flow paths (17, 18) for a fuel gas or a cathode gas, whereby the anode-side current collector (4a) together with the anode (1) and the cathode-side current collector (4b) together with the cathode (2) form an anode half cell (11) and a cathode half cell (12) respectively. According to the invention, the electrolyte matrix (3) or electrolyte layer is applied to one of the half cells (11, 12) and sealing elements (21, 22) are provided on the sides of the current collectors (4a, 4b) laterally surrounding the above in a sealing manner, whereby an insulating layer (31) electrically insulates each sealing element (21, 22) of a half cell (11) with respect to the other half cell (12).
