<P>PROBLEM TO BE SOLVED: To provide a fuel cell small in air flow rate distribution and small in temperature distribution and cell reaction distribution. <P>SOLUTION: A fuel cell system is equipped with a cuboid fuel cell stack in which an air inflow port is formed at the upper surface and an air exhaust port is formed at the lower surface; and an air supply duct in which an opening at one side is formed almost vertically to the upper surface of the fuel cell stack, an opening at the other side is connected to a frame-shaped peripheral part surrounding the air inflow port and its periphery, air is introduced from one side of the fuel cell stack in almost parallel to the upper surface of the fuel cell stack, and air is supplied to the air inflow port, and in the air supply duct, an opening at one side is arranged in the upper part higher than the upper surface of the fuel cell stack, and a member having an inclined plane is installed between the opening and the air inflow port. <P>COPYRIGHT: (C)2009,JPO&INPIT |
