Embodiment approach 1

[0043] [Structure of electrolysis device]

[0044]First, the configuration of the electrolysis device according to Embodiment 1 of the present invention will be briefly described. The electrolysis device of this embodiment is equipped with: the interior is filled with dissolved CO 2 The electrolytic cell of the electrolytic solution; the working electrode (WE), the counter electrode (CE) and the reference electrode (RE) installed in the electrolytic cell; a potentiostat configured to change the voltage of WE relative to RE. Since these components are components of a known electrolysis device, description thereof will be omitted.

[0045] In addition, the electrolysis device of the present embodiment is equipped with a control device that controls the voltage regulator to flow a predetermined current value between WE and CE to maintain the voltage of WE with respect to RE at a set value. In the internal memory of this control device, a set value of a voltage corresponding to ...

Embodiment approach 2

[0081] [Structure of electrolysis device]

[0082] Next, an electrolysis device according to Embodiment 2 of the present invention will be described. The electrolysis device of this embodiment is different from the configuration of the electrolysis device of Embodiment 1 above in that two electrolysis cells are provided. Therefore, since each component is basically the same as that of Embodiment 1 except for this point, description thereof will be omitted.

[0083] In the first embodiment described above, electrolysis was performed at the operation points B and C using one electrolytic tank. However, since the operating points B and C cannot be set at the same time, it is necessary to perform control to switch the operating point from B to C (or from C to B) at a certain point of time. In this regard, according to the present embodiment in which two electrolytic cells are provided, electrolysis at the operation point B and electrolysis at the operation point C can be perform...

Embodiment approach 3

[0086] Second, refer to image 3 Embodiment 3 of the present invention will be described. The present embodiment is characterized in that the order of electrolysis is determined according to the degree of reduction in energy efficiency by performing electrolysis using the structure of the above-mentioned first embodiment. Therefore, since each component is common to that of Embodiment 1 described above, description thereof will be omitted.

[0087] As described in Embodiment 1, when the voltage regulator is controlled so that a current flows between WE and CE, the reactions of the above formulas (1) to (3) are performed. If the reactions of the above-mentioned formulas (1) to (3) proceed, the reaction substances in the electrolytic solution will decrease. For example, if the reaction of the above formula (1) is carried out, the CO in the electrolyzer 2 Decrease, if the reaction of the above formula (2) is carried out, the protons will decrease. Thus, the concentration of t...

Abstract

This invention relates to a mixed gas generation device, and addresses the problem of providing a mixed gas generation device capable of energy-efficient generation of CO and H2. An energy-efficiency characteristic line (10) for electrolysis relative to the ratio of CO and H2 generated (CO / H2) is a downwardly convex curve. Thus, rather than at an operating point A which gives CO / H2 = 1 / 2, electrolysis occurs by divided an operating point B and an operating point C. Each of the electrolysis times is divided such that the generation ratio of the mixed gas having been mixed after electrolysis at each of the generation ratios becomes CO / H2 = 1 / 2. Accordingly, an energy efficiency in the vicinity of an operating point D which is higher than that of the operating point A can be achieved.

Description

technical field [0001] The present invention relates to a mixed gas generating device. In more detail, by combining water and CO 2 electrolysis to generate H 2 , A mixed gas generating device for a mixed gas composed of CO. Background technique [0002] Fossil fuels such as petroleum, coal, and natural gas are used as raw materials for generating heat and electricity, or as transportation fuels, supporting the modern energy-consuming society. However, such fossil fuels are fuels that will be exhausted, and their storage capacity is limited. It therefore goes without saying that there is a need to prepare for a scenario in which fossil fuels are depleted. In addition, it is known that CO produced by the combustion of fossil fuels 2 Emissions into the atmosphere are a major cause of global warming. Therefore, reducing CO 2 emissions have become an issue in recent years. [0003] As a method to solve these problems, the CO 2 Alternative fuels as raw materials. For exa...
