| Zusammenfassung: | The present invention relates to a fuel cell operation method in which a fuel cell that generates power using hydrogen gas and oxidant gas as reaction gas is operated at an operating pressure that corresponds to a required power generation state. A hydrogen sensor that detects hydrogen density is provided in a vicinity of the fuel cell, and based on values detected by the hydrogen sensor and on the amount of hydrogen leakage at the current operating pressure and on the characteristics of the fuel cell
11,
an operating pressure is predicted at which the hydrogen leakage amount from the fuel cell will not exceed a predetermined value, and the fuel cell is operated while limiting the operating pressure to below the predicted operating pressure. |
