Abstract

The invention relates to a fuel cell and/or an electrolyser comprising an electrolyte layer, one face of which is in contact with a cathode layer and the other face is in contact with an anode layer, the latter being connected electrically and/or mechanically to a first interconnector. According to the invention, a contact device is located in the vicinity of a free face of the cathode layer, said device being connected to both a second interconnector and the cathode layer in an electrically conductive and mechanical manner by means of a material union and/or a positive fit.
