Beschreibung
Zusammenfassung:	Disclosed is a highly reliable fuel cell having a long life which is capable of stably supplying electrical power without being affected by the circumstances and conditions under which it is operated. In a fuel cell comprising a fuel electrode (102) and an oxidant electrode (108), a moisture absorbing material (1051) is arranged in the vicinity of the oxidant electrode and the moisture absorbing material is moved close to, into contact with, or apart from the surface of the oxidant electrode. Consequently, the moisture absorbing material removes moisture from the oxidant electrode, thereby enabling the fuel cell to stably supply electrical power without being affected by the circumstances and conditions under which it is operated.
