Abstract

To improve stability and efficiency of a high-temperature solid-electrolyte fuel cell of planar multilayer design, it is proposed to increase the effective interface between the electrolyte layer and an electrode layer. This is achieved by a suitably treated surface of the electrolyte layer or by a porous and/or rough interlayer.
