Title:
PURE WATER TANK FOR FUEL CELL POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2005032626
Kind Code:
A
Abstract:
To prevent deformation and breakages of a pure water tank without thickening its plate thickness, with respect to volume expansion when freezing and increase in internal pressure when thawing, in the pure water tank for a fuel cell power generation system.
Ribs 17, 18 connecting to fix between the inside surface wall 14 and the outside surface wall 12 (and also in between adjacent walls 14) of an antifreeze solution tank 16 are arranged inside the antifreeze solution tank 16 of the pure water tank 10. These ribs 17, 18 have openings 17a, 18a in the direction of the gravity, and also form a passage 19 along the movement direction of an antifreeze solution.
