PURPOSE: A separator for fuel cell is provided to remove a flow-congestion region by minimizing the corner diameter of the channel bent part, thereby preventing droplet trap in the bent part, and widening electrode active area. CONSTITUTION: A separator for fuel cell(100) comprises a channel(11) for flowing reactive gas in one side. The channel is formed to be curvy. A protrusion(71) is formed in the bent part. When compartmentalize the bent part to in-course and out-course, the protrusion is formed to be projected from a corner part of the in-course to the out-course. The separator consists of metallic thin plate material, and forms the channel through a stamping process. |
