Abstract
The present invention relates to a fuel cell devised to uniformly distribute and supply a reformed gas (or an oxidant or a coolant) while minimizing the increase in parts number, without making the construction complicated. The present invention has a gist of providing a fuel cellpiling up, by way of separators, multiple cellsand providing, in the stackinner manifolds for distributing (or supplying or discharging) to these cellsa fuel, an oxidant or a coolant, wherein: a cylindrical/tubular piercing memberis provided in at least one inner manifoldand a proper gap is provided between the piercing memberand an inner wall of the inner manifoldThe reformed gas supplied to the inner manifoldbefore being distributed to each cellis flow-regulated by the piercing memberThus, the reformed gas is distributed uniformly to each cella stable power generation is done, and performance of the fuel cell can be improved.
