PROBLEM TO BE SOLVED: To provide a fuel battery system capable of continuously supplying fuel gas to a fuel battery even when a requested power generation amount is small.SOLUTION: The fuel battery system comprises: a fuel battery stack 10; a fuel gas supply flow passage in which hydrogen is circulated; a fuel gas circulation flow passage for circulating the hydrogen; a first injector 24 provided on the fuel gas supply flow passage on an upper stream side than a connection point of the fuel gas circulation flow passage, and emitting the hydrogen; a bypass flow passage connecting the fuel gas supply flow passage on an upstream side of the first injector 24 to the fuel gas supply flow passage on a downstream side of the first injector 24, and bypassing the hydrogen to the first injector 24; small flow rate supply means provided on the bypass flow passage and constituted so that the hydrogen can be continuously supplied at a small flow rate; region determination means for determining whether the requested power generation amount is in a low load region or not; and control means for controlling the first injector 24. When the region determination means determines the requested power generation amount as the low load region, the control means stops the first injector 24, and the small flow rate supply means continuously supplies fuel gas at a small flow rate. |
