Abstract
A fuel cell stack 10 includes a stacked structure 14 composed of a plurality of electricity-generating cells stacked successively, and dummy cells arranged at both ends in a stacking direction of the stacked structure 14. Each dummy cell 16 each includes a conductive plate 52 and first and second metallic separators 54, 56 which sandwich the conductive plate 52. The conductive plate 52 is formed of a metallic plate having substantially the same shape as that of the electrolytic membrane electrode assembly 22. The first and second metallic separators 54, 56 are structured in the same manner as the first and second metallic separators 24, 26 of the electricity-generating cell 12.
