Abstract
A fuel cell includes a multi-layered cell assembly having a stacked plurality of unit cells. Each unit includes a plate-like electrolyte layer having an oxygen electrode on one face thereof and a fuel electrode on the other face thereof, an oxygen-containing gas passage facing the oxygen electrode and a fuel gas passage facing the fuel electrode. An exhaust gas passage is formed adjacent end faces of the stacked unit cells. The oxygen-containing gas passage discharges oxygen-containing gas to the exhaust gas exhaust passage, whereas the fuel gas passage discharges fuel gas to the exhaust gas exhaust passage. The oxygen-containing gas passage includes an oxygen-containing gas passage extension portion for forming an oxygen-containing gas passage exit opening remotely from the end face of the unit cell, and the fuel gas passage includes a fuel gas passage extension portion for forming a fuel gas passage exit opening remotely from the end face of the unit cell.
