燃料電池システム
Document Type and Number:
Japanese Patent JP6954157
Kind Code:
B2
Abstract:
To eliminate the surge of a compressor while supplying an oxidizing gas required for power generation according to a load when there is a load demand for a fuel cell.SOLUTION: In a case in which there is no load demand on a fuel cell when the operating state of a compressor enters a surge region where a surge occurs, the opening of a second valve is increased to increase the flow rate of an oxidizing gas flowing through a bypass passage, and therefore, the pressure ratio between the input and output of the compressor is reduced, and when there is a load demand on the fuel cell, the opening of a first valve is increased to increase the flow rate of the oxidizing gas flowing through the cathode, and therefore, the pressure ratio between the input and output of the compressor is reduced.SELECTED DRAWING: Figure 3
