Abstract
A fuel cell system includes a fuel cell stack, a heat exchanger, a reformer, and a casing containing the fuel cell stack, the heat exchanger, and the reformer. A chamber unit is formed at an end plate of the fuel cell stack. The air heated by the heat exchanger temporarily fills the chamber unit. The heat exchanger and the reformer are directly connected to the chamber unit.
Claims10
A fuel cell system comprising:
- a fuel cell stack including a plurality of fuel cells stacked together in a stacking direction and end plates provided at opposite ends of said fuel cells in the stacking direction, said fuel cells each including an electrolyte electrode assembly and separators sandwiching said electrolyte electrode assembly, said electrolyte electrode assembly including an anode, a cathode, and an electrolyte interposed between said anode and said cathode;
- a heat exchanger for heating an oxygen-containing gas to be supplied to said fuel cell stack;
- a reformer for reforming a fuel to produce a fuel gas;
- a casing containing said fuel cell stack, said heat exchanger, and said reformer,
- wherein a chamber unit is formed at one of said end plates, and the oxygen-containing gas heated by said heat exchanger temporarily fills said chamber unit;
- and
- said heat exchanger and said reformer are directly connected to said chamber unit.
