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 cell5,piling up, by way of separators, multiple cells1,and providing, in the stack2,inner manifolds for distributing (or supplying or discharging) to these cells1a fuel, an oxidant or a coolant, wherein: a cylindrical/tubular piercing member4is provided in at least one inner manifold6,and a proper gap is provided between the piercing member4and an inner wall of the inner manifold6.The reformed gas supplied to the inner manifold6,before being distributed to each cell1,is flow-regulated by the piercing member4.Thus, the reformed gas is distributed uniformly to each cell1,a stable power generation is done, and performance of the fuel cell can be improved.
