Title:
固体高分子型燃料電池用セパレータ製造装置及び製造方法
Document Type and Number:
Japanese Patent JP4231399
Kind Code:
B2
Abstract:
To provide a separator for a solid polymer fuel cell with a low cost and high durability, which is capable of improving the characteristics of the cell by reducing a contact resistance thereof by increasing a contact area of an indented part with an electrode.
The separator for a solid polymer fuel cell has a flat part at a peripheral part, and indented parts serving as gas passages at the part excluding the flat part. An angle between a vertical wall part of the indentation and a horizontal part is 100° or less, and the contact area with the electrode is 30% or more of a projected area of an electrode part forming the gas flow passage.
