Problems solved by technology

[0008] In the previous electrochemical element having the above structure, when utilizing the water activity difference between the two electrodes 2 and 3 to recycle electric energy, even if the humidity on one side of the output voltage is 100% and the humidity on the other side is 10%, 10% is generated. times poor activity, but the output voltage is as low as several millivolts, so there is a problem that it is difficult to increase the output voltage

Embodiment approach 1

[0020] figure 1 Shown is a configuration diagram of the first embodiment. figure 1 Among them, 5 is a solid electrolyte membrane, which is a solid electrolyte with hydrogen ion conductivity. The solid electrolyte membrane 5 is, for example, Nafion-117 (registered trademark) manufactured by Dupont Corporation. 6 is a first electrode with a catalytic function and hydrophilicity formed on one side of the solid electrolyte membrane 5, which is formed by alloying two metal components with different oxidation tendencies, oxidizing the metal component with a high oxidation tendency and It is formed by dispersing oxide fine particles 6a on the surface and pressing them to the solid electrolyte membrane 5 . In the formation of the first electrode 6, for example, an alloy formed by solid solution of Ti with 20 (atom)% in Pt with catalytic function and power supply function is subjected to heat treatment at 500°C in pure oxygen at 900 atmospheric pressure, such as figure 2 Only Ti ...

Embodiment approach 2

[0034] Figure 5 Shown is a configuration diagram of Embodiment 2. Figure 5 In , the portion indicated by 5 is the same as that in Embodiment 1. 9 is a first electrode formed on one side of the solid electrolyte membrane 5, which consists of a reaction part 9a with a catalytic function on the adjacent side of the solid electrolyte membrane 5 and a hydrophilic part 9b on the surface of the reaction part 9a. constitute. Furthermore, the hydrophilic portion 9b is formed by capillarity by enlarging the ratio of the depth direction to the pore diameter of a porous metal obtained by plating platinum on the surface of titanium, for example. 10 is the second electrode formed on the other side of the solid electrolyte membrane 5, which is composed of a catalytic reaction part 10a on the adjacent side of the solid electrolyte membrane 5 and a hydrophobic hydrophobic part 10b on the surface of the reaction part 10a. . Moreover, the hydrophobic portion 10b is, for example, made of CF...

Embodiment approach 3

[0040] Image 6 Shown is a configuration diagram of the third embodiment. Image 6 In , the portion indicated by 5 is the same as that in Embodiment 1. 12 is the first electrode with catalytic function formed on one side of the solid electrolyte membrane 5 by the Pt electroless plating method, and its surface is endowed with hydrophilicity by irradiation of at least one of plasma, vacuum ultraviolet light and ozone. Also, the first electrode 12 may be imparted with hydrophilicity by depositing and adhering a substance having a hydrophilic group. 13 is the second electrode with catalytic function formed by Pt electroless plating method on the other side of solid electrolyte membrane 5, which is made of any one of organic compound and organic fluorine compound as raw material by CVD method, sputtering method, evaporation method, etc. It is formed by depositing and adhering hydrophobic components on the surface by either plating method or dipping method. For example, hydrophob...

Abstract

Making a larger difference in water activity between electrodes elevates an output voltage of an electrochemical element. The electrochemical element includes a solid electrolyte membrane 5 made of a solid electrolyte and possessing a hydrogen ion conductivity, a first electrode 6 formed on one side of the solid electrolyte membrane 5 and functioning as a catalyst and possessing a hydrophilic property, and a second electrode 7 formed on the other side of the solid electrolyte membrane 5 and functioning as a catalyst and possessing a water-repellent property.

Description

technical field [0001] The present invention relates to an electrochemical element using a solid electrolyte for energy exchange between chemical energy and electrical energy. Background technique [0002] Figure 9 It is a structural diagram of an electrochemical element described in, for example, JP-A-6-63343 as an energy conversion element using a solid electrolyte. Figure 9 Among them, a solid electrolyte membrane 1 having hydrogen ion conductivity is formed with a first electrode 2 on one side and a second electrode 3 on the other side. In addition, the solid electrolyte membrane 1 is, for example, Nafion-117 (registered trademark) manufactured by Dupont Corporation. The first electrode 2 is a mixed layer composed of platinum-plated stainless steel fiber with power supply function, titanium porous metal plate, platinum black with catalytic function, and solid electrolyte components. In addition, the second electrode 3 is a mixed layer composed of platinum-coated stain...
