Zusammenfassung: | A metal separator for a fuel cell is provided to prevent the obstruction of the fluid flux through an oiling pipe by forming a sub-flow channel having small width and small cross-sectional area compared with the oiling pipe. A metal separator(100) for a fuel cell is manufactured though a stamping molding process by using two metallic thin films. A cooling channel is formed at the inner side of a first metallic thin film(101) and a second metallic thin film(102) in stamping molding. The respective first and second oiling pipes(104, 105) are formed at the outer side of the first and the second metallic thin films. The respective first and second subsidiary flow channels (107, 108) are formed on the floor side of the first and the second oiling pipes. |
