Abstract: The invention relates to an anode and electrolyte and cathode in direct material contact in fuel cell applications, so that the anode and electrolyte, and the cathode and electrolyte, particularly at temperatures >400° C., can react in a solid chemical manner. Said reaction results in that the material of the anodes can diffuse into the electrolyte and vice versa, and the material of the cathodes can diffuse into the electrolyte or vice versa. The effect thereof is the modification of the electrical energy yield of the fuel cells. In order to prevent said effect, it is proposed according to the invention that a blocking layer is disposed between the electrolyte and anode and electrolyte and cathode and is made of areas having opened and closed pores and that the functional penetration paths for the diffusion are formed by the frame structure thus created.
