A hollow-fiber membrane module for moisture exchange including a tubular outer case, a tubular inner case, plural hollow-fiber membranes, sealing portions, an inlet, an outlet, a first flow path, a second flow path, and a tubular porous member. The inner case is coaxially contained in the outer case so as to have a space therebetween. The hollow-fiber membranes are filled in the space and extend in the axial direction. The sealing portions are provided to both ends of the space so as to fix the plural hollow-fiber membranes and to seal the space. The first flow path extends from one end side of the hollow-fiber membranes to the other end side via insides of the hollow-fiber membranes. The second flow path extends from the inlet to the outlet via outsides of the hollow-fiber membranes in the space. The tubular porous member is inserted between the hollow-fiber membranes.

A fuel cell system includes a branch anode gas supply pipe in which hydrogen before supplied to a fuel cell flows; and a branch cathode gas supply pipe in which air before supplied to the fuel cell flows. One end on the upstream side of the branch anode gas supply pipe is connected to the upstream side of a regulator in an anode gas supply pipe, and the other end thereof is connected to the branch cathode gas supply pipe via a hydrogen injector. The branch anode gas supply pipe is provided with a hydrogen regulator, which detects a pressure in the branch cathode gas supply pipe as a signal pressure.
