Abstract:
1. A fuel cell system comprising: a fuel cell configured to generate electric power by making a fuel gas supplied to a fuel electrode and an oxidant gas supplied to an oxidant electrode electrochemically react with each other; a fuel gas supply unit configured to supply the fuel electrode with the fuel gas through a fuel gas supply passage; a first open/close device provided in the fuel gas supply passage and configured to change an open/closed state of the fuel gas supply passage; a second open/close device provided in the fuel gas supply passage at a position downstream of the first open/close device and configured to change an open/closed state of the fuel gas supply passage; a bypass passage, a first end of which is connected to the fuel gas supply passage at a position between the first open/close device and the second open/close device, and a second end of which is connected to the fuel gas supply passage at a position between the second open/close device and the fuel cell; a flow rate limitation device provided in the bypass passage and configured to limit a flow rate of the gas flowing through the bypass passage; and a controller configured
