Regulation Of Fluid Flow In A Fuel Cell Stack

Abstract: ABSTRACT “REGULATION OF FLUID FLOW IN A FUEL CELL STACK” Present disclosure discloses a bipolar plate (100) for a fuel cell. The bipolar plate (100) includes a first inlet (102) extending along an edge of the bipolar plate (100) to 5 receive a first fluid. A plurality of first corrugations (114) are defined on the bipolar plate (100) proximal to the first inlet (102). The plurality of first corrugations (114) comprises a plurality of first crests (116) and a plurality of first troughs (118) extending in an alternating configuration. Each of the plurality of first troughs (118) is to be in contact with a corresponding trough of another bipolar 10 plate of the fuel cell that is disposed below the bipolar plate. The plurality of first corrugations (114) are configured to receive a gasket (122) on the bipolar plate (100) to restrict flow of the first fluid across a surface of the bipolar plate (100). Fig. 3a is the representative figure.

Specification

We Claim:
1. A bipolar plate (100) for a fuel cell, the bipolar plate (100) comprising:
a first inlet (102) extending along an edge of the bipolar plate (100) to receive a
first fluid;
5 a plurality of first corrugations (114) defined on the bipolar plate (100) proximal to
the first inlet (102), wherein the plurality of first corrugations (114) comprises a plurality
of first crests (116) and a plurality of first troughs (118) extending in an alternating
configuration, wherein each of the plurality of first troughs (118) is to be in contact with a
corresponding trough of another bipolar plate of the fuel cell that is disposed below the
10 bipolar plate, and
wherein the plurality of first corrugations (114) are configured to receive a
gasket (122) on the bipolar plate (100) to restrict flow of the first fluid across a
surface of the bipolar plate (100).
15 2. The bipolar plate (100) as claimed in claim 1, wherein the bipolar plate (100) is defined
with a second inlet (402) defined along the edge of the bipolar plate (100) and positioned
adjacent to the first inlet (102), wherein the second inlet (402) is configured to receive a
second fluid.
20 3. The bipolar plate (100) as claimed in claim 2, wherein the bipolar plate (100) comprises a
plurality of second corrugations (450) proximal to the second inlet (402), and are defined
with a plurality of second crests (451) and a plurality of second troughs (452) extending in
the alternating configuration, wherein each of the plurality of second troughs (452) is to be
in contact with a corresponding trough of another bipolar plate (106) of the fuel cell (302)
25 that is disposed below the bipolar plate (100), and the plurality of second corrugations
(450) are configured to receive a gasket (122) on the bipolar plate (100) to restrict flow of
the second fluid across the first flow channel (112).
4. The bipolar plate (100) as claimed in claim 2, wherein the bipolar plate (100) is defined
30 with a first
