Embodiment 1

[0080] Hydrogen was produced by the hydrogen production apparatus having the structure shown in FIG. 1 as follows. In reaction vessel 1, an internal volume of 65 cm was used 3 , PP made of prismatic container. Aluminum pipes with an inner diameter of 2 mm and an outer diameter of 3 mm were used for the hydrogen outlet pipe 1b and the water supply pipe 1c. The water storage container 2 also has the same structure and structure as the reaction container 1, and the water supply pipe 2b and the water recovery pipe 2c also use aluminum pipes similar to the water supply pipe 1c and the like. The loading and unloading mechanism 3 has a structure in which the respective tubes of the reaction container 1 and the water storage container 2 are inserted into a cylindrical portion with an inner diameter of 3.5 mm on the side of the hydrogen production apparatus. A ring is arranged at each cylindrical portion to suppress leakage of hydrogen and water from the loading and unloading mechani...

Embodiment 2

[0089] Using the same hydrogen production apparatus as in Example 1, the generated hydrogen was supplied to a fuel cell to generate electricity. In the experiment, an electrode area of ​​22cm was used 2 A solid polymer fuel cell composed of six units connected in series. When a load was connected and discharged at a constant voltage of 3.9V, a high output of about 14W was obtained, showing that the hydrogen production device of the present invention is effective as a fuel source for a small, portable fuel cell. In addition, it is clear from the results of Example 1 that the hydrogen production device of the present invention can continuously supply hydrogen to the fuel cell for a long time, so by using the fuel cell system incorporating the hydrogen production device of the present invention as a power source of electronic equipment, It can make the equipment operate stably for a long time.

Abstract

The present invention provides a hydrogen producing apparatus which can safely and continuously produce hydrogen and a fuel cell system using the apparatus as hydrogen supply source. The electronic equipment using the fuel cell system as the power source can be used for long time. The hydrogen producing apparatus can be attachably and detachably provided with a reactor for accommodating the hydrogen generating substance of the hydrogen generated by the reaction of water, a water container for containing water, and a mechanism for supplying water in the water container to the reactor. A measuring device for measuring at least one of a hydrogen generation rate from the reactor and a temperature of the reactor is provided. Removal of the reactor is restricted according to a measurement value of the measuring device.

Description

technical field [0001] The present invention relates to a hydrogen production device for producing hydrogen by reacting a hydrogen generating substance with water, a fuel cell system using the hydrogen production device as a hydrogen supply source, and an electronic device including the fuel cell system. Background technique [0002] In recent years, with the spread of wireless devices such as computers and mobile phones, there has been an increasing demand for smaller and higher-capacity batteries as their power sources. Currently, lithium-ion secondary batteries are put into practical use as batteries capable of achieving high energy density, small size and light weight, and demand for portable power sources is increasing. However, this lithium ion secondary battery has a problem that a sufficient continuous use time cannot be guaranteed for some wireless devices. [0003] In order to solve the above-mentioned problems, the development of fuel cells such as solid polymer ...
