Japanese Patent JP6972633
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system which can contribute to improvement of generation efficiency in a fuel cell by supplying water produced by chemical reaction appropriately to the fuel cell.SOLUTION: A fuel cell system 100 has a fuel cell 1 for obtaining electrical power by causing chemical reaction of hydrogen and oxygen, a radiator 4 for cooling the fuel cell 1 by heat exchange with cooling water, a gas/liquid separator 10 for recovering moisture content produced in the fuel cell 1, a humidification flow path 15 for disseminating water recovered in the gas/liquid separator 10 to the fuel cell 1, a radiator side flow path 14 for disseminating the recovered water to the radiator 4, and a controller 16. When a determination is made that the fuel cell 1 is in a dry state, operation of a dissemination pump 12 and a flow rate adjustment valve 13 is controlled, and the recovered water is disseminated to the fuel cell 1. By controlling a magnetic valve 19 when disseminating recovered water to the fuel cell 1, cooling water supply to an intercooler 17 is stopped, and cooling performance of the intercooler 17 is decreased.SELECTED DRAWING: Figure 1
