Example Embodiment
[0040] The following describes the embodiments of the present invention in detail. The examples of the embodiments are intended to explain the present invention, but should not be understood as a limitation to the present invention.
[0041] The hydrogen production method provided by the present invention includes: contacting iron powder and oxygen-containing water vapor, the water vapor in the oxygen-containing water vapor reacts with the iron powder to generate ferroferric oxide and hydrogen, and the oxygen-containing water vapor Oxygen reacts with iron powder to generate iron oxide and release heat. The released heat provides heat for the reaction between water vapor and iron powder so that the water vapor and iron powder continue to react. Wherein, the oxygen-containing water vapor is preferably obtained by the following method: normal temperature water is pressurized to 3-5 bar and then atomized, and then mixed with oxygen and heated with a heat source provided by hydrogen ge...
