SEPARATOR FOR FUEL CELL AND METHOD FOR FORMING COLLECTOR CONSTITUTING THE SEPARATOR

摘要

A separator (10) is constituted of a separator main body (11), and a collector (12). The main body (11) prevents a mixed flow of a fuel gas and an oxidizing agent gas. The collector (12) is formed of metal lath MR where the angle between the forming direction of a strand portion (through hole forming portion) for forming meshed through holes stepwise and the forming direction of a bond portion (connecting portion) for connecting the strand portions is set at about 60 degrees. Consequently, the pitch P of the collector (12) is decreased and the plate thickness can be increased. Good gas supply performance is thereby assured by reducing pressure loss of an introduced gas, and water produced in an MEA (30) by capillarity between trough holes can be drained well.
