Abstract (en)

[origin: DE19835253A1] A manufacturing method for a high-temperature fuel cell equipped with a contact layer (16) between the cathode (14) and bipolar plate (18). For manufacture of the contact layer (18), a contact material is applied to the bipolar plate (18) and then subjected to a high temperature, esp. over 800 deg. C. Before application of the contact material, a pore forming agent is added, and specifically remains insoluble in the contact material, the latter being a ceramic silk-screen paste or a ceramic injection moulded suspension.
