Abstract
A power generation cell includes a frame member. The frame member includes a first frame shaped sheet and a second frame shaped sheet that are joined together. The second frame shaped sheet is provided outside a cathode through a gap. A method of operating a fuel cell includes supplying a first reactant gas to a channel formed between the frame member and a first separator, a pressure of the first reactant gas being higher than a pressure of a second reactant gas, and supplying the second reactant gas to a channel formed between the frame member and a second separator.
