Abstract
A fuel cell system includes: a fuel supply unit supplying a fuel; an air supply unit supplying air; a stack including a membrane electrode assembly (MEA) having an air path and a fuel path; a gas-liquid separator connected to an outlet of the fuel path and an outlet of the air path for separating gas-liquid into high-temperature liquid and moisture gas; a mixer mixing the high-temperature liquid separated by the gas-liquid separator and a fuel supplied from the fuel supply unit and connecting the gas-liquid separator and the MEA; a moisture absorbent connected to the gas-liquid separator to absorb condensed liquid in the high-temperature moisture gas; and a heat exchanger to vaporize the liquid absorbed by the moisture absorbent.
