GAS SUPPLY DEVICE, HYDROGEN STATION, AND GAS SUPPLY METHOD

摘要

An object of the present invention is to suppress a gas pressure in an accumulator (30) from dropping. A gas supply device (10) includes a first compressor (22) that compresses hydrogen gas, an accumulator disposed downstream of the first compressor and supplying the hydrogen gas to a dispenser (12) that fills the hydrogen gas in a vehicle (14), and a gas flow passage (16) that connects the first compressor, the accumulator, and the dispenser, and a control device (58). The gas flow passage (16) includes a lead-in line (18a) for leading the hydrogen gas into the accumulator, a lead-out line (18b) for leading out the hydrogen gas from the accumulator, a lead-in side valve (34), and a lead-out side valve (38). The control device (58) is configured to be capable of simultaneously bringing the lead-in side valve and the lead-out side valve into an open state.
