Claims

[Scope of utility model registration request]

A unit cell having a fuel electrode and an oxidizer electrode facing each other with an electrolyte matrix interposed therebetween, and a gas separation plate having a gas passage supplying a reactive gas to each of the electrodes and a reservoir supplying an electrolyte solution to the electrolyte matrix are alternately arranged. In a stacked fuel cell in which a plurality of fuel cells are stacked on each other, each of the reservoirs is communicated with each other through an electrolyte supply hole, and the electrolyte permeates into the electrolyte holding material filled in each of the reservoirs, the electrolyte is distributed in the longitudinal direction of the reservoir. A stacked fuel cell characterized in that a groove extending in the longitudinal direction is provided at the bottom of the reservoir to ensure a passage for circulation.
