ABSTRACT:
Arrangement of fuel cells based on a high-temperature solid electrolyte (1) of stabilized ZrO.sub.2 for achieving maximum possible power in minimum space by electrical series connection and mechanical stacking of a plurality of flat, plane plate-shaped fuel cells (1; 2; 3) on the filter press principle, in each case the oxygen electrode (2) of the one fuel cell being connected to the fuel electrode (3) of the next-following fuel cell by an electrically conductive element (4), which contains flow channels for the gaseous media. Design of the electrically conductive elements as a bipolar plate (4) provided with elevations (11). Cross-flow principle. Chequerboard-like arrangement of a plurality of fuel cell stacks (33) next to one another: best utilization of space, maximum power density.
