Provided is a gas supply system in which the pressure of a compressed gas can be reduced in a stable state and the resulting gas can be supplied, as well as the system has an excellent economy and safety, wherein the pressure of a gas supplied from a source of a compressed gas (high-pressure gas container 11) is reduced by a pressure reducing means (pressure regulator 21, 31) and the resulting gas is supplied, wherein, on the upstream side, in the gas flow direction, of the pressure reducing means, a heat exchanger 22, 32 which heats the gas by heat exchange of a gas introduced to the pressure reducing means and warm water supplied from a warm water source (warm water circulation unit 15) is provided, as well as, in the pressure reducing means, a warm water flow channel 53 for heating the pressure reducing means by a part of the warm water is provided. |
