Abstract
A fuel cell system includes a fuel cell stack, a heat exchanger, a reformer, and a combustor. A combustion gas path for supplying the combustion gas produced in the combustor to the heat exchanger as the heat medium is provided. The combustion gas path is provided between a space of dual walls comprising a first inner plate and a second inner plate and a first case unit and a second case unit accommodating a load applying mechanism and the fuel cell stack.
Claims7
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 being formed by stacking an electrolyte electrode assembly and a separator, 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 using a heat medium before the oxygen-containing gas is supplied to said fuel cell stack;
- a reformer for reforming a raw fuel chiefly containing hydrocarbon to produce a fuel gas to be supplied to said fuel cell stack;
- a combustor for burning the raw fuel to produce a combustion gas, wherein
- a fluid unit including at least said heat exchanger and said reformer is provided at one end of said fuel cell stack in the stacking direction, and said combustor is provided at the other end of the fuel cell stack in the stacking direction;
- a combustion gas path for supplying the combustion gas produced in said combustor to said heat exchanger as the heat medium;
- and
- said combustion gas path is provided in a space between dual walls comprising an inner wall and an outer wall, accommodating said fuel cell stack.
