Title:
液位検知装置、燃料電池システム
Document Type and Number:
Japanese Patent JP6892596
Kind Code:
B2
Abstract:
To provide a liquid surface detector that can suppress reduction in the volume of the liquid stored in a storage and can also restrain the resistance of flowing of a fluid, and a fuel cell system.SOLUTION: A fuel cell system 1 has a liquid surface detector 50 which is allowed to detect the liquid surface in a storage 41 in such a manner that a sensor substrate 52 in the shape of a thin plate provided with a detector 53 detecting changes of heat fluxes on a surface 521 is set on the inner surface wall 421 of the storage 41. The controller 100 in the fuel cell system 1 is configured to discharge water stored in the storage 41 by controlling opening/closing of a discharge valve 37 on the basis of the result of detection of the liquid surface detector 50.SELECTED DRAWING: Figure 1
