Abstract: A hydrogen mixed gas generation method using a device that includes a heating pipe housing therein a reduction acceleration member and a heating part including a heating device that heats the heating pipe includes a first process and a second process. The first process includes: causing raw water to flow into the heating pipe and heating the flowing raw water to generate water vapor; heating the generated water vapor to between 500° C. to 800° C.; causing the heated water vapor to be in contact with the reduction acceleration member that is heated along with the raw water to reduce the water vapor and generate hydrogen gas. The second process includes: diluting the hydrogen gas generated in the first process to obtain hydrogen mixed gas whose concentration of hydrogen gas is between 500 ppm to 20000 ppm.

Abstract: A hydrogen mixed gas generation apparatus includes a superheated vapor heating part that heats a raw water to generate a superheated vapor and further heats the superheated vapor to produce a mixed gas that includes a hydrogen gas, and a communication part that is communicable with a predetermined terminal device and transmits information to the terminal device. The superheated vapor heating part houses a reduction acceleration member and includes a heating pipe where the raw water flows therein, and a coil heater that is wound around the heating pipe. The reduction acceleration member includes a first metal member that is formed of a stainless steel and includes a cylindrical part where rod bodies respectively extend from both ends thereof and a second metal member that is formed of an iron and steel material and is housed in the cylindrical part in a state where a plurality thereof are bundled.
