Embodiment 1

[0084] Specific examples of the fuel cell device of the present invention are described below. SiC particles are impregnated with Ni(NO 3 ) 2 After being placed in an aqueous solution of a silicon carbide, nickel particles are supported on silicon carbide by drying, firing and hydrogen reduction. The supported amount of nickel is about 5% by mass when the mass of silicon carbide is 100%. About 15 g of silicon carbide supporting nickel was filled in a stainless steel container. The internal volume of the container is set at about 200cm 3 . Use this vessel as a decomposition reactor for hydrocarbons. 180 g of liquefied butane was filled in the reservoir. The internal volume of this reservoir is set at approximately 300cm 3 . Then use this to form an integrated storage and decomposition reactor.

[0085] Alumina particles were impregnated with Pt(NH 3 ) 4 (ON) 2 After being placed in an aqueous solution of aluminum oxide, platinum particles are carried on alumina thro...

Embodiment 2

[0091] From the fuel cell device that stopped working in Example 1, the integrated storage and decomposition reactor were separated. Then, a new storage and decomposition reactor of the same integrated type as in Example 1 was combined with the fuel cell again. Then by opening the fuel valve, with about 50mlmin -1 The amount of butane supplied. After 30 seconds, an output of 20W was generated by connecting the fuel cell to a load. Under this condition, the fuel cell device can work continuously and stably for 21.7 hours with an output of 20W. Thereafter, since the output of the fuel cell becomes unstable, the load of the fuel cell is cut off to stop the power generation.

[0092] According to Example 2, it was confirmed that the fuel cell device of the present invention using an integrated storage device filled with butane and a decomposition reactor enables repeated use of the device by exchanging the integrated storage device and decomposition reactor. .

Embodiment 3

[0094] A fuel cell device is equipped with a storage tank with 180g of liquefied butane, a stainless steel decomposition reactor with 7.5g of nickel-supported silicon carbide, an oxidation reactor with a catalyst active in the oxidation reaction, and a fuel cell. . Here the internal volumes of the storage, decomposition reactor and oxidation reactor are set to be 300 cm 3 , 100cm 3 and 40cm 3 . The accumulator here, the preparation method of decomposition reactor and oxidation reactor are identical with embodiment 1, and the inner volume of the decomposition reactor here is 1 / 2 of the occasion of embodiment 1. Here, since the storage tank and the decomposition reactor are independent structures, the decomposition reactor can be separately separated or combined.

[0095] The same steps as in Example 1 are used to make the fuel cell device work. First, supply of butane and air to the oxidation reactor was started. Butane supply is set to 10ml min -1 , after about 10 minut...

Description

technical field [0001] The present invention relates to a fuel cell device having a container for decomposing hydrocarbons into hydrogen and carbon using a catalyst. technical background [0002] A fuel cell is an electrochemical device that generates electricity by electrochemically reacting hydrogen at the anode and oxygen at the cathode. Respectively, the electrochemical reaction shown in formula (1) occurs at the anode, and the electrochemical reaction shown in formula (2) occurs at the cathode. In a fuel cell, electricity can be extracted directly from the fuel's hydrogen. That is to say, in the fuel cell, since there is no restriction of the Carnot cycle, the power generation efficiency of the battery is very high. In addition to high power generation efficiency, fuel cells also have the characteristics of high output power density, and their discharge does not contain carbon dioxide and nitrogen oxides. Therefore, fuel cells are attracting attention as the next gene...
