Claims (29)

1. A container comprising:

a first plate;

a second plate spaced from the first plate and movable in respect of the first plate; and

at least one rail extending between the first plate and the second plate, the rail having a plurality of seal blocks disposed thereon, wherein each of the seal blocks includes at least one seal disposed thereon, and wherein the at least one seal of each of the seal blocks contacts a surface of a bipolar plate to form a fluid-tight seal therebetween.

2. The container according to claim 1 , wherein the second plate is linearly movable in respect of the first plate.

3. The container according to claim 1 , wherein each of the seal blocks includes a fastening portion adapted to be received on the rail and a sealing portion adapted to be removeably attached to the fastening portion.

4. The container according to claim 3 , wherein the sealing portion of the seal blocks includes the at least one seal disposed thereon.

5. The container according to claim 1 wherein the seal blocks are produced from polytetrafluoroethylene.

6. The container according to claim 1 , further comprising a clamp to militate against movement of the second plate relative to the first plate.

7. The container according to claim 1 , further comprising a band to interconnect the first plate, the second plate, and the seal blocks.

8. The container according to claim 1 , further comprising a testing coupon secured to at least one of the first plate and the second plate.

9. A container comprising:

a first outer plate;

a second outer plate spaced from the first outer plate;

at least one rail extending between the first outer plate and the second outer plate, the rail having a plurality of seal blocks disposed thereon, wherein each of the seal blocks includes at least one seal disposed thereon, and wherein the at least one seal of each of the seal blocks contacts a surface of a bipolar plate to form a fluid-tight seal therebetween;

a first inner plate disposed on the rail; and

a second inner plate spaced from the first inner plate and linearly movable in respect to the first inner plate, wherein the first inner plate and the second inner plate are disposed on the rail intermediate the first outer plate and the second outer plate, and wherein the seal blocks are disposed on the rail intermediate the first inner plate and the second inner plate.

10. The container according to claim 9 , further comprising a band to interconnect the first inner plate, the second inner plate, and the seal blocks.

11. The container according to claim 9 , wherein each of the seal blocks includes a fastening portion adapted to be received on the rail and a sealing portion adapted to be removeably attached to the fastening portion.

12. The container according to claim 11 , wherein the sealing portion of the seal blocks includes the at least one seal disposed thereon.

13. The container according to claim 9 , wherein the seal blocks are produced from polytetrafluoroethylene.

14. The container according to claim 9 , further comprising a clamp to militate against movement of the second inner plate relative to the first inner plate.

15. The container according to claim 9 , further comprising a testing coupon secured to at least one of the first outer plate, the second outer plate, the first inner plate, and the second inner plate.

16. A container for a dip coating process comprising:

a first plate;

a second plate spaced from the first plate and linearly movable in respect to the first plate; and

at least one rail extending between the first plate and the second plate, the rail having a plurality of seal blocks disposed thereon, wherein each of the seal blocks includes a fastening portion adapted to be received on the rail and a sealing portion adapted to be removeably attached to the fastening portion, the sealing portion including at least one seal disposed thereon, wherein the at least one seal of the sealing portion contacts a surface of a bipolar plate to form a fluid-tight seal therebetween.

17. The container according to claim 16 , wherein the at least one seal of the sealing portion surrounds a channel header of the bipolar plate to form a fluid-tight seal therebetween.

18. The container according to claim 16 , further comprising a testing coupon secured to at least one of the first plate and the second plate.
