1. A hydrogen gas mixing device, comprising:
a water electrolysis part configured to generate a hydrogen gas and an oxygen gas by electrolysis of water;
a mixing gas supply part configured to supply a mixing gas;
a gas mixing part configured to mix the hydrogen gas and the mixing gas; and
a dilution gas supply part including a pressure container that stores a non-combustible dilution gas in a compressed state and being configured to supply the non-combustible dilution gas,
wherein the mixing gas supplied from the mixing gas supply part or the non-combustible dilution gas stored in the pressure container is introduced into an oxygen flow part of the water electrolysis part through which the oxygen gas flows.
