Abstract
Abstract A fuel cell having an electrolytic layer (1), an oxygen electrode (2) attached to one face of the electrolytic layer, a fuel electrode (3) attached to the other face of the electrolytic layer, a separator (4) formed of electrically conductive material and disposed in opposition to the oxygen electrode to be electrically connected therewith, an oxygen-containing gas flow passage (a) formed between the oxygen electrode and the separator, and a conductive member (5) disposed in the oxygen-containing gas flow passage. The conductive member is formed of flexible material and separately from the oxygen electrode and the separator for connecting entire or partial faces respectively of the oxygen electrode and the separator with each other.
