Assembly for a fuel cell and method for producing same

The arrangement has an adaptation layer (AD) provided for adaptation of electrolyte (E) to electrodes and arranged between the electrodes and the electrolytes, where middle porous dimension of the adaptation layer is smaller than that of the electrodes. The adaptation layer exhibits a central surface smoothness of maximum 1.0 micrometer. The electrodes are designed as an anode and cathode. The adaptation layer exhibits thickness that ranges from 3 to 7 micrometer. The adaptation layer and the electrolytes are made of electronic non-conducting material. An independent claim is also included for a method for manufacturing the fuel cell arrangement.
