Abstract (en)
[origin: WO2005093887A2] In order to improve a tightness between different cells (5) forming a planar geometry fuel cell (1), low-porous or nonporous areas (11) are arranged in an electrode layer (10) around a gas supply connection (2). The formation of an interlocking connection (18, 22) between a bipolar plate (20) and a three-layer ceramic element (10, 20) which forms a base cell (5) and makes it possible to prevent a gas mixtures is also disclosed.
