Title:
燃料電池システム
Document Type and Number:
Japanese Patent JP6637870
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system capable of properly preventing performance deterioration of a fuel cell stack during power generation stop, with a simple structure.SOLUTION: A fuel cell system 100 includes a fuel cell stack 1 performing power generation, a hydrogen tank 3, a hydrogen supply passage L2 provided between the fuel cell stack 1 and the hydrogen tank 3, an injector 4 provided in the hydrogen supply passage L2, and adjusting the pressure of hydrogen flowing into the fuel cell stack 1, a bypass passage L3 having one end on the upstream side connected with the upstream of the injector 4, and the other end on the down stream side connected with the downstream of the injector 4, and connected with the hydrogen supply passage L2 while bypassing the injector 4, and a relief valve 11 provided in the bypass passage L3. The relief valve 11 is in an open state when the pressure of hydrogen in the upstream of the relief valve 11 is higher than the pressure of hydrogen in the downstream of the relief valve 11, with a pressure difference of a predetermined pressure Pc or more.SELECTED DRAWING: Figure 1
