Title:
METAL SEPARATOR FOR FUEL CELL AND POWER GENERATION CELL
Document Type and Number:
Japanese Patent JP2019061754
Kind Code:
A
Abstract:
To provide a metal separator for fuel cell capable of restraining variation of seal surface pressure in a bead seal, and to provide a power generation cell.SOLUTION: In a first metal separator 30, a first bead structure 52 for preventing leakage of reaction gas is formed to project in the thickness direction of the separator. The first bead structure 52 has two rows of bead seal (continuous hole bead part 53 and an outer peripheral side bead part 54), between the separator outer end edge 30e and a part of an oxydant gas entry continuous hole 34a on the separator outer end edge 30e side. When viewing from the thickness direction of the separator, one of the two rows of bead seal is wave form, and the other is linear.SELECTED DRAWING: Figure 4
