A solid oxide fuel cell includes a plurality of electric power-generating
elements stacked in a stack direction, each including a solid oxide
electrolyte and a porous electrode section. A plurality of first current
collector layers are connected to the porous electrode sections,
respectively. At least one separator is provided for separating the
plurality of electric power-generating elements. A gas supply channel is
defined between the at least one separator and is associated with one of
the plurality of first current collector layers. A plurality of gas
supply branch passages branch off from the gas supply channel and reach
the electrode section of the associated one of the plurality of electric
power-generating elements. The fuel cell further includes a plurality of
gas exhaust channels for exhausting consumed gas via the associated one
of the plurality of first current collector layers.
