PURPOSE:To increase efficiency and to ensure safety by accommodating a cell main body, a fuel reformer, a d.c.-a.c. converter, an electrical equipment housing board in a unit casing and mutually utilizing exhaust heat and ventilation in each chamber. CONSTITUTION:A fuel cell unit casing 1 is partitioned into an electrical equipment chamber a and cell chamber b with a partition 6. A d.c.-a.c. converter 2 and an electrical equipment housing board 5 are installed in the electrical equipment chamber a, and the outside air introduced through a forced fan 8 cools the inside of the chamber a and forced into the cell chamber b through a vent hole 9. Exhaust heat from the electrical equipment chamber a is utilized for a cell main body 3 and a fuel reformer 4, and the forced air is exhausted from the casing 1 together with leaked gas from the cell main body 3. Exhaust heat from the fuel reformer 4 is utilized for the cell main body and the reformer 4 itself. |
