Thus, the air in the external space S3 where the snow 50, a pebble, and the like are not included is taken in by the air compressor. The air is introduced from the bypass path 16 as indicated by a blank arrow in FIG. 3, so as to reach the space S1A between the chemical filter 3 and the filter element 2 through the opening 18, and then, the air passes through the second prefilter 5 provided in the space S1A. After that, dust, particulate matter, and the like are removed from the air by the filter element 2, so that the air is sent out from the outlet 15 to the supply pipe 32, as indicated by a black arrow in FIG. 3.

As such, with the air cleaner 1 of the present embodiment, even when the snow 50 taken in with the air is deposited inside the air cleaner case 11, clean air from which foreign matter is removed is supplied to the fuel cell stack. This accordingly makes it possible to restrain power generation from being stopped, thereby making it possible to continue the running of the fuel cell vehicle.

The present embodiment is different from Embodiment 1 in that a filter element of an air cleaner 21 is a charged filter 22. The following mainly describes differences from Embodiment 1.

FIG. 4 is a sectional view schematically illustrating the air cleaner 21 for a fuel cell vehicle according to the present embodiment. The air cleaner 21 is provided with the first prefilter 4, the chemical filter 3, the second prefilter 5, and the charged filter 22 sequentially from the upstream side.
