Abstract
When a shutoff signal is entered to shut off a fuel gas manufacturing apparatus, it is determined whether a PSA mechanism is in a prescribed shutoff state or not. If the PSA mechanism is judged as not being in the prescribed shutoff state, the fuel gas manufacturing apparatus is continuously operated until the PSA mechanism is brought into the prescribed shutoff state. Then, if the PSA mechanism reaches the prescribed shutoff state, the fuel gas manufacturing apparatus is shut off.
