ABSTRACT:
A fuel cell having a heat exchanger that has a structure suitable for reducing space occupancy of the fuel cell. The fuel cell includes a stack where a chemical reaction for transforming chemical energy of a fuel into electricity occurs and a heat exchanger that removes heat generated during the energy transformation process in the stack, wherein the heat exchanger is built in at least one plate mounted on the stack. Therefore, the occupancy of the fuel cell can be reduced to be approximately half of a conventional externally mounted type heat exchanger.
