Problems solved by technology

For example, the electrolyte in alkaline aqueous fuel cells is potassium hydroxide, the electrolyte in acidic aqueous fuel cells is phosphoric acid, the electrolyte in molten carbonate fuel cells is lithium carbonate or potassium carbonate, and the electrolyte in solid oxide fuel cells The electrolyte is stabilized zirconia, and the electrolyte in solid polymer fuel cells is an ion exchange membrane. The use of electrolyte layers is essential. In fact, the existence of these electrolyte layers hinders the miniaturization and low price of fuel cells. realization of

Embodiment 1

[0328] In this embodiment, the following devices were used as the hydrogen-based-oxygen-based mixed gas generation device shown in Figs. 65-67.

[0329] (A) Vibration stirring device

[0330] Produced by Japan Technology Co., Ltd., the trade name is Ultra Vibration α-Stirrer α-1 Type (an insulated vibrating mixer, the current flowing in the electrolyte will not flow to the vibrating motor).

[0331] Vibration motor: 75W×200V×3 phase

[0332] Low-frequency vibration motor manufactured by Murakami Seiki Co., Ltd.

[0333] The product name is ユラスバイブレタター

[0334] Vibrator: 2 pieces of SUS304 with a diameter of 16mm

[0335] Vibration vanes: 4 pieces made of SUS304 with a thickness of 6mm

[0336] Fixing parts: made of SUS304

[0337] Elastic member sheet: a sheet with a trade name of Teflon (registered trademark)

[0338] (B) Fixed electrode

[0339] Positive electrode: 27 platinum-plated titanium plates

[0340] Negative electrode: 24 titanium plates

[0341] (C) Inverte...

Embodiment 2

[0365] Unlike Example 1, the gas generated by the electrolyzer passes through the safety device and is directly delivered to the fuel cell, but the hydrogen-oxygen mixed gas in Example 1 generated by the electrolyzer is stored in the gas storage tank After standing for one day, instead of passing through the sealed tank in Fig. 59 and the fireproof groove in Fig. 60, the above-mentioned hydrogen-oxygen-based mixed gas (raw gas) is directly supplied to the hydrogen gas supply port of the fuel cell in Example 1, and the same can be obtained. Example 1 has the same effect. Furthermore, the same analysis as above was carried out on this raw gas, and as a result, almost the same data as the analysis results of the above-mentioned raw gas were obtained. In particular, it was confirmed that H and H 3 , HD, and OH are the same.

Embodiment 3

[0367] In this example, the following devices were used for the hydrogen-oxygen mixed gas generator using the vibrating stirring device shown in FIG. 50 .

[0368] (A) Vibration Stirring Device (Insulated Vibration Stirring Device)

[0369] Manufactured by Nippon Techno Co., Ltd., the product name is Ultra Vibration α-Mixer (Type α-2)

[0370] Vibration motor: 150W×200V×3 phase

[0371] Vibrator: SUS304 diameter 16mm, 2 pieces

[0372] Vibration vane: SUS304 thickness 6mm, 5 pieces

[0373] Auxiliary blade for electrodes

[0374] Plate negative side: 3 made of SUS304

[0375] Positive plate side: Platinum-plated (thickness 10μm) 2 pieces made of SUS304

[0376] (B) Inverter: manufactured by Fuji Electric Co., Ltd., product name is FVR-E11S

[0377] Adjust to 55Hz for use.

[0378] (C) Rectifier: Hi-Mini, 200V manufactured by Chuo Works

[0379] (D) Electrolyzer: made of SUS304

[0380] The inner diameter is 220mm×320mm×400mm(H)

[0381] The inner surface is covered w...

Abstract

A unit cell composed of a fuel electrode, an air electrode, and an electrolyte layer or hollow layer disposed between the electrodes, or a fuel battery comprising a stack of such unit cells. The fuel battery is such that a supply port for supplying hydrogen-based / oxygen-based mixture gas produced by electrolyzing an electrolyte while vibrating and stirring it and collecting the produced gas is provided on the fuel electrode side, and the fuel electrode to which the mixture gas is supplied is gas-permeable. The hydrogen-based / oxygen-based mixture gas contains H, H2, H3 and / or HD, OH, <16>O, and O2.

Description

technical field [0001] The present invention relates to a new hydrogen-oxygen mixed gas and hydrogen-based gas obtained by electrolyzing an electrolytic solution under vibration and stirring, a fuel cell fuel composed of them, a power generation method using the fuel cell fuel, and The fuel cell. Background technique [0002] Conventionally, power generation by a fuel cell is performed by supplying hydrogen to a fuel electrode (usually a negative electrode) and supplying oxygen or air to an air electrode (usually a positive electrode). The reason for this is the consideration that if hydrogen is not supplied to the fuel pole, it will not be possible to propel [0003] 2H 2 →4H + +4e - [0004] reaction, and does not occur if oxygen or an oxygen-containing gas such as air is not supplied to the air electrode [0005] o 2 +4H + +4e - →2H 2 o [0006] Reaction. [0007] As a related art, JP-A-2002-348694 describes a method of using Brown gas as a fuel for a fuel cel...
