An air cleaner for a fuel cell vehicle, according to the disclosure, is configured such that a projection projecting toward the inside of a case is provided, and a chemical filter and protective members provided on the upstream side and the downstream side of the chemical filter are sandwiched between the projection and a filter element, so that the chemical filter is firmly fixed to the case.

More specifically, the disclosure relates to an air cleaner for a fuel cell vehicle, the air cleaner including a case and a filter element. The case has an inlet and an outlet. The filter element is fixed to the case, and configured to section the case into an inlet side and an outlet side and filter air flowing from the inlet side to the outlet side.

The air cleaner is configured such that: a locking projection projecting toward the inside of the case is provided on the inlet side in the case; and a first protective member and a second protective member each having permeability, and a chemical filter configured to adsorb a molecular substance included in the air are sandwiched between the locking projection and the filter element inside the case in an order of the first protective member, the chemical filter, and the second protective member from an upstream side that is the inlet side of the filter element inside the case toward a downstream side that is the outlet side of the filter element inside the case.
