Document Type and Number:
Japanese Patent JP7126610
Kind Code:
B2
Abstract:
A separator-integrated gasket is provided for making an electrolyte membrane unlikely to be deformed when a stack is assembled. The separator-integrated gasket for a fuel battery includes a lip-shaped gasket, first and second separator components, and a flat-shaped gasket. The first and second separator components are made of press-workable metal plates, and include first and second three-dimensional shape portions, respectively. The first separator component includes a surface that is on a side opposite to a protruding direction of the first three-dimensional shape portion and on which a gasket attachment groove holding the lip-shaped gasket is formed. The second separator component includes a surface that is on a side opposite to a protruding direction of the second three-dimensional shape portion and on which a three-dimensional shape fitting groove accommodating the first three-dimensional shape portion is formed. The flat-shaped gasket is held on an outer surface side at the second three-dimensional shape portion. The first and second three-dimensional shape portions protrude in the same direction while mutually adjusted in positions on a flat surface. The first and second separator components are joined to each other while superposed over each other in a thickness direction.
