## 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.

## Claims

### Claim 1

A hydrogen mixed gas generation apparatus, comprising:
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, based on a preliminarily set condition, information that corresponds to the condition, to the terminal device, wherein
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, and
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.

### Claim 2 (depends on 1)

The hydrogen mixed gas generation apparatus according to claim 1, wherein the second metal member includes a pipe member and a plurality of rod-shaped members that are bundled around the pipe member.

### Claim 3 (depends on 2)

The hydrogen mixed gas generation apparatus according to claim 2, wherein a diameter of the pipe member is greater than diameters of the rod-shaped members.

### Claim 4 (depends on 1)

The hydrogen mixed gas generation apparatus according to claim 1, wherein lengths of the rod bodies that extend from the cylindrical part in the first metal member are defined in such a manner that the cylindrical part does not contact the raw water.

### Claim 5 (depends on 1)

The hydrogen mixed gas generation apparatus according to claim 1, further comprising
a casing that is formed into a rectangular box shape, wherein
the casing is formed to be partitioned into a first housing chamber and a second housing chamber that is provided on a bottom of the first housing chamber through a partition wall, and
a functional part that includes at least the superheated vapor heating part is housed in the first housing chamber and a transformer is housed in the second housing chamber.
