Abstract

A fuel cell case containing a fuel cell stack includes a side face that has an opening for ventilation; a frame body that is located outside of the case along the periphery of the opening; and a louver that is fixed to inside of the frame body. The louver has a plurality of blades arranged to be separated from one another. The fuel cell case also has a projection that is protruded outward of the case in a predetermined range including at least a region located on a gas blow direction side of the louver in an inner peripheral portion of the frame body. This configuration reduces the likelihood that an elongated material such as wire comes into contact with a high-voltage component relevant to the fuel cell inside of the case.

First claim

1 - 5 . (canceled)

6 . A fuel cell case that contains a fuel cell, the fuel cell case comprising
a wall member that has an opening for ventilation; and a ventilation cover that is provided at the opening of the wall member, wherein the ventilation cover comprises: a frame body that is located outside of the case along periphery of the opening; a louver that has a plurality of blades arranged to be separated from one another and is fixed to inside of the frame body; and a projection that is provided to be protruded outward of the case in a predetermined range including at least a region located on a gas blow direction side of the louver in an inner peripheral portion of the frame body.

7 . The fuel cell case according to claim 6 , wherein the projection is protruded from an entire circumference of the inner peripheral portion of the frame body.

8 . The fuel cell case according to claim 7 , further comprising a waterproof, gas-permeable membrane that is provided in the opening.

9 . The fuel cell case according to claim 8 ,
wherein a plurality of the openings and a plurality of the ventilation covers are provided in one wall member constituting the case, and at least one of the ventilation covers has the louver arranged in a different direction from a direction of the louver in another ventilation cover.

10 . The fuel cell case according to claim 7 ,
wherein a plurality of the openings and a plurality of the ventilation covers are provided in one wall member constituting the case, and at least one of the ventilation covers has the louver arranged in a different direction from a direction of the louver in another ventilation cover.

11 . The fuel cell case according to claim 6 , further comprising
a waterproof, gas-permeable membrane that is provided in the opening.

12 . The fuel cell case according to claim 11 ,
wherein a plurality of the openings and a plurality of the ventilation covers are provided in one wall member constituting the case, and at least one of the ventilation covers has the louver arranged in a different direction from a direction of the louver in another ventilation cover.

13 . The fuel cell case according to claim 6 ,
wherein a plurality of the openings and a plurality of the ventilation covers are provided in one wall member constituting the case, and at least one of the ventilation covers has the louver arranged in a different direction from a direction of the louver in another ventilation cover.

14 . A ventilation cover that is mounted to a case opening of a fuel cell case containing a fuel cell, the ventilation cover comprising:
a frame body that is located outside of the case along periphery of the case opening; and a louver that has a plurality of blades arranged to be separated from one another and is fixed to inside of the frame body, wherein a projection is provided to be protruded outward of the case in a predetermined range including at least a region located on a gas blow direction side of the louver in an inner peripheral portion of the frame body.
