Separator for fuel cell and fuel cell including the same
There are provided a separator for a fuel cell and a fuel cell including the same able to enhance the horizontal distribution of fuel or an oxidizing agent and secure an effective flow area, the separator including: a separator body; a first intake manifold provided at one end portion of the separator body; a second intake manifold provided at the other end portion of the separator body to be partitioned from the first intake manifold; a first exhaust manifold provided outwardly of the second intake manifold at the other end portion of the separator body; and a second exhaust manifold provided outwardly of the first intake manifold at one end portion of the separator body to be partitioned from the first exhaust manifold.
1. A separator for a fuel cell, comprising:
a separator body;
a first intake manifold provided at one end portion of the separator body;
a second intake manifold provided at the other end portion of the separator body to be partitioned from the first intake manifold;
a first exhaust manifold provided outwardly of the second intake manifold at the other end portion of the separator body; and
a second exhaust manifold provided outwardly of the first intake manifold at one end portion of the separator body to be partitioned from the first exhaust manifold,
wherein the first intake manifold and the second exhaust manifold are arranged in separate rows in a longitudinal direction perpendicular to a width direction of the separator body at one end portion of the separator body, and the second intake manifold and the first exhaust manifold are arranged in separate rows in the longitudinal direction perpendicular to the width direction of the separator body at the other end portion of the separator body,
wherein the first exhaust manifold and the second exhaust manifold are elongated in the width direction of the separator body.
2. The separator for a fuel cell of claim 1 , wherein the separator body is provided with one or more of the first and second intake manifolds.
3. The separator for a fuel cell of claim 2 , wherein the separator body has a circulation path between the first intake manifold and the first exhaust manifold in the interior thereof.
4. The separator for a fuel cell of claim 1 , wherein the separator body has a circulation path between the first intake manifold and the first exhaust manifold in the interior thereof.
5. A fuel cell comprising one or more unit cells stacked therein,
wherein the unit cell includes the separator for a fuel cell of claim 1 , the separator comprising a plurality of separators, and
the separators for a fuel cell are stacked to intersect perpendicularly to allow fuel or an oxidizing agent to intersect and circulate.
6. A fuel cell of claim 5 , wherein the separator body has a circulation path between the first intake manifold and the first exhaust manifold in the interior thereof.
7. The fuel cell of claim 6 , wherein the circulation path allows a gas supplied by the first intake manifold to pass between the second intake manifolds and be discharged through the first exhaust manifold.
8. The fuel cell of claim 5 , wherein the second intake manifold of the separator is connected to a first intake manifold of another separator by sealing, and
the second exhaust manifold of the separator is connected to a first exhaust manifold of another separator by sealing.
