[0025] Referring to FIGS. 1 and 2, a module for fueling a hydrogen cell by using a hydrogen production and purification device comprises a hydrogen production device 10, a hydrogen purification device 30 and a hydrogen cell power generation system 20. The hydrogen production device 10 comprises: a housing 11, a cavity 113 being formed in the housing 11, and a first opening 111, a second opening 112 and a third opening 114 which all communicate with the cavity 113 being formed in the housing 11; a plasma generating unit 12 contained in the cavity 113 and comprising a first electrode 121 and a second electrode 122, the first electrode 121 being close to the first opening 111, the second electrode 122 being close to the second opening 112, and a plasma column 16 being formed between the first electrode 121 and the second electrode 122; a voltage supply unit 15, a power supply end of the voltage supply unit 15 being electrically connected to the first electrode 121 and the second electrode 122, and a potential difference exists between the first electrode 121 and the second electrode 122 to generate plasma; a feeding unit 13 communicating with the first opening 111; and an exhaust unit 14, an input end of the exhaust unit 14 communicating with the second opening 112, and the exhaust unit 14 being used for allowing air in the cavity 113 to generate an air current flowing from the first opening 111 to the second opening 112 via the second opening 112, so that the plasma between the first electrode 121 and the second electrode 122 is affected by the air current to form the plasma column. An input end of the hydrogen purification device 30 communicates with an output end of the exhaust unit 14. The hydrogen cell power generation system 20 communicates with an output end of the hydrogen purification device 30.

[0026] In this embodiment, a position of the third opening 114 is lower than a height of the first electrode 121.

[0027] The feeding unit 13 comprises a receiving chamber 131 and an oscillator 132, the receiving chamber 131 is used for receiving a hydrogen-containing substance, and the oscillator 132 is used for making contact with the hydrogen-containing substance.

[0028] The hydrogen-containing substance is ammonia liquid. The exhaust unit 14 is an air pump.

[0029] The voltage supply unit 15 is used for supplying an alternating current to the first electrode 121 and the second electrode 122, the frequency of the alternating current is 2-20 kHz, and the voltage of the alternating current is 4000-14000 V.

[0030] The working principle of the module for fueling the hydrogen cell by using the hydrogen production and purification device provided by the invention is as follows:

[0031] The housing 11 is provided with a third through hole for air circulation, so that a small amount of air may be stored in the housing 11. The ammonia solution is added into the receiving chamber 131 of the feeding unit 13, and the oscillator 132 is in contact with the ammonia solution. The oscillator 132 may be a piezoelectric element that generates high-frequency oscillation, so that the liquid ammonia solution forms a plurality of fine liquid particles, which are scattered in the housing 11 or enter the housing 11 with an air current. The first electrode 121 and the second electrode 122 are connected to the voltage supply unit 15, and the voltage supply unit 15 supplies the alternating current to the first electrode 121 and the second electrode 122, wherein the frequency of the alternating current is 2-20 kHz, and the voltage is 4000-14000 V. The air and the liquid particles of the ammonia solution are mixed between the first electrode 121 and the second electrode 122, and a plasma chemical reaction occurs under the action of the plasma column between the first electrode 121 and the second electrode 122. The reaction process is as follows: the plasma column 16 has many charged particles in a high-energy free state, and when entering the housing 11, the liquid particles of the ammonia solution will be impacted by the charged particles, which will destroy a carbon-hydrogen bond, thus generating hydrogen components; and the hydrogen-containing substance is decomposed into hydrogen components, which are delivered to the hydrogen purification device 30 through the exhaust unit 14, and the hydrogen purified by the hydrogen purification device 30 is transferred to the hydrogen cell power generation system 20, wherein the hydrogen purification device 30 uses electrolytic hydrogen as a raw material, which is subjected to catalytic deoxidization, cooling, adsorption and secondary drying, and then passes through a filter to remove impurities such as oxygen, water vapor and dust in the hydrogen to obtain high-purity hydrogen. The purity of high-purity hydrogen in a product may reach over 99.9995%, which is the prior art and will not be described in detail.

[0032] The above embodiments are only used to explain the technical solution of the invention, but not to limit it. Those skilled in the art should understand that any modifications and equivalent substitutions that do not depart from the spirit and scope of the invention shall fall within the protection scope of the Claims of the invention.
