Claim 5:
6. A separator sealing apparatus for bonding an upper separator and a lower separator with an electrode plate being interposed therebetween, the separator sealing apparatus comprising:
a first sealing unit configured to seal a first region of the upper separator and the lower separator along a width direction of the electrode plate where the upper separator and the lower separator face each other; and
a second sealing unit configured to seal a second region of the upper separator and the lower separator along a length direction of the electrode plate where the upper separator and the lower separator face each other,
wherein the first sealing unit is configured to seal another first region of the upper separator and the lower separator along the width direction of the electrode plate, and the first sealing unit includes:
a pair of first upper heating blocks configured to apply pressure and heat to the first regions of the upper separator, the pair of first upper heating blocks being spaced apart from each other at an interval to extend in one direction side by side; and
a pair of first lower heating blocks configured to apply pressure and heat to the first regions of the lower separator, the pair of first lower heating blocks are arranged opposite the pair of first upper heating blocks,

wherein the second sealing unit is configured to seal another second region of the upper separator and the lower separator along the length direction of the electrode plate, and the second sealing unit includes:
a plurality of second upper heating blocks respectively configured to extend in a direction intersecting with the first upper heating block and coupled to the pair of first upper heating blocks at locations spaced apart from each other at an interval along an extending direction of the pair of first upper heating blocks to apply heat and pressure to the second regions of the upper separator; and
a plurality of second lower heating blocks provided to be symmetric with the second upper heating blocks in one-to-one relationship and coupled to the pair of first lower heating blocks to apply heat and pressure to the second regions of the lower separator.
