Abstract
A solid oxide fuel cell includes a separator which has a fuel gas passageway and an oxidant gas passageway thereinside, and a plurality of power generation cells arranged in a parallel connection state on the same plane. Each of the power generation cells has a solid electrolyte layer sandwiched between a fuel electrode layer and an oxidant electrode layer. The oxidant gas passageway may start at an edge portion of the separator, extend to a central portion of the separator at a position enclosed by the power generation cells, be divided at the central portion, and be introduced in a portion facing the respective oxidant electrode layer.
