A fuel cell (A1) includes a cell stack (B) and a casing (210) for housing the cell stack (B), and is supplied with two reactant gases flowing separately from each other. The cell stack (B) includes a plurality of solid electrolyte fuel cell units (200) stacked on one another with inter-unit spaces provided therebetween. One of the reactant gases is supplied to the inter-unit spaces and used for power generation. The casing (210) includes a peripheral wall (222) surrounding the cell stack (B). The peripheral wall (222) is provided with at least one gas inlet opening (223) for introducing the one of the reactant gases into the inter-unit spaces and at least one gas outlet opening (224) for discharging the introduced reactant gas, wherein total opening width dimension of the gas inlet opening (223) is greater than total opening width dimension of the gas outlet opening (224).

Solid oxide fuel cells each include a circular cell plate holding single cells as a solid oxide fuel cells and having a gas introducing opening and a gas exhausting opening in a central section. A circular separator plate has a gas introducing opening and a gas exhausting opening in a central section. Sealing members allow the gas intruding openings of the cell plate and the separator plate to airtightly communicate with each other and allow the gas exhausting openings of the cell plate and the separator plate to airtightly communicate with each other.

A fuel cell includes a stack structure composed of fuel cell units with current collectors between the fuel cell units, a casing housing the stack structure, and a gas flow-regulating member provided in a gap between the casing and the stack structure. The fuel cell unit includes: a cell plate which holds at least one cell and has a gas introduction hole for one of fuel gas and air; and a separator plate which has a gas introduction hole for the one of the fuel gas and the air. The casing introduces the other of the fuel gas and the air via a gas introduction portion and flows the other gas to a gas discharge portion. The gas flow-regulating member guides the other gas to the gas discharge portion through the current collectors.
