Abstract

A fuel cell for a vehicle includes seats disposed on a side of a separation plate and having a recessed bottom and inclined sides connecting the edges of the bottom and the separation plate at an angle. Gaskets are projected along the seats on the side of the separation plate. Fastening bars are seated in the seats with the gaskets projected thereon, in the shape of a strip fastening the fuel cell and have a body being in close contact with the bottom and flanges being in close contact with an inclined side.

First claim

What is claimed is:

1. A fuel cell for a vehicle, comprising:
a groove formed on one side of a separation plate, the groove having a recessed bottom and inclined sides which are connected to ends of the recessed bottom, respectively, at an angle;
a gasket covering the groove along the one side of the separation plate; and
a fastening bar disposed on an upper portion of the gasket while the gasket is disposed on an upper portion of the groove to cover the groove, the fastening bar having a strip shape and including:
a body, which is in close contact with the gasket covering the recessed bottom; and
flanges, which are end portions of the body and which extend upwardly, being in close contact with the gasket that covers the inclined sides at ends of the body, respectively,

wherein the end portions extend from the ends of the body in a longitudinal direction of the fastening bar.

2. The fuel cell of claim 1 , wherein the gasket covers and extends along the one side of the separation plate while covering the groove.

3. The fuel cell of claim 1 , wherein the body of the fastening bar has a length corresponding to a length of the recessed bottom of the groove.

4. The fuel cell of claim 1 , wherein the flanges of the fastening bar each have a length corresponding to a length of each of the inclined sides of the groove, respectively.

5. The fuel cell of claim 1 , wherein an angle between the body and the flange of the fastening bar is larger than the angle between the end of the recessed bottom and the inclined sides of the groove, respectively.
