Abstract: A fuel cell employs a stack structure in which a plurality of sheet bodies and a plurality of separators are stacked and joined together in alternating layers. Chemical reactions occur in the sheet bodies. The separators separate, from each other, two kinds of gasses (air and fuel gas) which are necessary for the chemical reactions. The plurality of separators consist of high-rigidity separator(s), and ordinary separators, which are lower in rigidity than the high-rigidity separator. This configuration reliably suppresses the occurrence of “separation of a joint region” attributable to “stress concentration caused by increase in the number of the stacked separators.
