There is provided a fuel cell having a prolonged life by uniformly causing a hydrogen ionization reaction to occur at a fuel electrode, a fuel cell power generation device using the same, and the system using the same as well. There is also provided a method for operating a fuel cell in which a plurality of unit cells are stacked, each of the unit cells including a fuel electrode to which a fuel containing hydrogen as a major component is supplied, an air electrode to which air is supplied as an oxidizing agent, and an electrolyte provided between the fuel electrode and the air electrode. This operation method is characterized in that the number of moles of oxygen contained in air supplied to the air electrode is controlled based on the measured value such as number of moles of hydrogen contained in the incoming or outgoing fuel from the cell. |
