Abstract

A fuel cell includes an electrolyte electrode assembly and separators. The separator includes first through third plates which are stacked together. The first plate has a first protrusion section on its surface contacting an anode of a first circular disk. The first protrusion section includes a large number of protrusions and a substantially ring shaped protrusion which is provided around the protrusions. The first protrusion section protrudes toward the anode, and a fuel gas flow field is formed between the anode and the first protrusion section.
