PURPOSE: To uniformly supply fuel to respective unit cells by straightening the fuel flow in a distributing passage to distribute the fuel to the unit cells constituting a fuel cell. CONSTITUTION: A fuel gas supply passage and an oxidizing gas supply passage 12 to supply fuel gas and oxidizing gas to respective unit cells are formed in a fuel cell 10 by layering the unit cells. An upstream straightening member 70 composed of a porous body having a three-dimensional mesh structure is arranged in the vicinity of a through hole 62 of an end plate 60 forming an inflow port of the fuel gas supply passage and the oxidizing gas supply passage 12 by arranging a clearance with the end plate 60, and a downstream straightening member 72 is arranged by arranging a clearance with the upstream straightening member 70. The fuel gas and the oxidizing gas flow are straightened by the upstream straightening member 70 and the downstream straightening member 72, and are uniformly supplied to the respective unit cells. As a result, the respective unit cells can be made highly efficient and uniform, and can be formed as a highly efficient fuel cell. |
