<p>A method of manufacturing a separator for fuel cell, comprising the steps of forming separators (41, 95, 107) with cores by providing cores (31, 94) between two preforms (17, 90, 101), and heating the separators to fuse and discharge the cores so as to form a plurality of cooling water passages (54), whereby the need of sealing can be eliminated since the separators must not be stuck on each other to form the cooling water passages, and since the separators must not be stuck on each other, an electric contact resistance is also lowered.</p> |
