<P>PROBLEM TO BE SOLVED: To respectively seal a fuel gas, an oxidizer gas, and a cooling medium well, and to achieve thinning of a laminating direction as much as possible. <P>SOLUTION: In a fuel cell 10, unit cells 12a, 12b are alternately laminated. The unit cell 12a pinches a first electrolyte membrane/electrode assembly 20a by a first metal separator 22 and a second metal separator 24. At the second metal separator 24, a first seal part 74a for a fuel gas sealing, a second seal part 74b for an oxidizer gas sealing, and a third seal part 74c for a cooling medium sealing are installed, and the first sealing part 74a, the second sealing part 74b, and the third sealing part 74c are arranged mutually offset against the laminating direction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
