<P>PROBLEM TO BE SOLVED: To reduce pressure loss generated at boundaries between stripe-shaped or linear fluid flow passages composed of a plurality of convex parts and concave parts contiguous to each other in wave-shape, and distribution flow passages for distributing reaction gas or cooling water to be introduced to the plurality of fluid flow passages. <P>SOLUTION: The separator for fuel cell 20 has stripe-shaped flow passages formed on a face of the separator composed of convex parts 21a and concave parts 21b contiguous to each other in wave-shape, and distribution flow passages 12 distributing the fluid to be introduced to the fluid flow passages 10 therein. At the boundary of the linear fluid flow passage 10 and the distribution flow passage 12, the position of end of the convex parts 21a and that of the concave parts 21b constituting the fluid flow passage 10 are arranged so as to be staggered from each other in a direction of stripe of the fluid flow passage 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
