Brennstoffzellenanlage mit Festelektrolyten

摘要

A solid-electrolyte fuel cell system includes a plurality of fuel cells stacked to form a cell assembly. Each cell has an electrolyte layer (1), an oxygen electrode (2) applied to one surface of the electrolyte layer, a fuel electrode (3) applied to the other surface of the electrolyte layer, an oxygen-containing gas passage (S) opposed to the oxygen electrode, and a fuel gas passage (f) opposed to the fuel electrode. An oxygen-containing gas supply passage (Si) is disposed at one end of the cell assembly, as seen in a stacking direction of the fuel cells, to communicate with the oxygen-containing gas passage. Fuel gas supply passages (fi) are disposed at opposite sides of the cell assembly. A combustion chamber (K) is disposed at the other end of the cell assembly to communicate with the oxygen-containing gas passage and fuel gas passage for burning an oxygen-containing gas exhausted from the oxygen-containing gas passage and a fuel gas exhausted from the fuel gas passage.
