Patent ID: 8338047

Claim:
A solid oxide fuel cell comprising: a fuel cell stack having alternately laminated power generation cells and separators, the power generation cells and the separators alternating in a laminating direction of the fuel cell stack; a reactant gas passage extending through each of the separators; and a reactant gas supply manifold extending through the fuel cell stack in the laminating direction for supplying reactant gas to each of the power generation cells, the manifold being in fluid communication with the gas passages of the separators so as to supply the reactant gas through the gas passages to each of the power generation cells, wherein the manifold is in fluid communication with the gas passages of the separators through a gas-flow throttle mechanism, wherein the gas-flow throttle mechanism comprises a plurality of through-holes, the through-holes extending through the separators, respectively, wherein each of the separators has a first surface facing in the laminating direction and a second surface on an opposite side of the separator from the first surface, and the gas passage extending through each separator is confined between the first surface and the second surface thereof, and wherein the gas passage extending through each separator penetrates the first surface at a discharge point for discharging the reactant gas to the power generation cells.
