Abstract
A fuel cell system includes a fuel cell stack. The fuel cell stack includes a plurality of fuel cells stacked together in a stacking direction, and end plates provided at opposite ends of the fuel cells in the stacking direction. A fluid unit is provided on one side of the fuel cell stack. The fluid unit includes a heat exchanger for heating an oxygen-containing gas to be supplied to the fuel cell stack, and a reformer for reforming a fuel to produce a fuel gas.
Claims19
A fuel cell system comprising:
- a fuel cell stack formed by stacking a plurality of fuel cells in a 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;
- and
- a casing containing said fuel cell stack, said heat exchanger, and said reformer,
- wherein a fluid unit including at least said heat exchanger and said reformer is provided on one side of said fuel cell stack in said casing.
