Definitions
- Portable fuel cells, portable devices and fuel cartridges are Portable fuel cells, portable devices and fuel cartridges
- the present invention relates to a portable fuel cell, a portable device, and a fuel cartridge, and more particularly to a fuel cartridge integrated with an air filter.
- Fuel cells have attracted attention as batteries for portable devices such as mobile phones, portable information terminals, and notebook computers.
- Lithium secondary batteries are widely used as secondary batteries for mobile devices.
- Fuel cells have the potential to increase the energy density compared to lithium secondary batteries.
- fuel cells generate only moisture and carbon dioxide and use much less heavy metals than chemical cells, so their environmental impact can be significantly reduced.
- DMFC direct methanol fuel cell
- DDFC direct dimethyl ether fuel cell
- the portable fuel cell as described above directly converts chemical reaction energy between fuel and oxygen in the air, which is an oxidant, into electric energy. Therefore, a reformer or the like for extracting hydrogen from the fuel is not required, and miniaturization and weight reduction can be easily achieved (see Patent Documents 11 to 13).
- dust of about 0.01 to 10 ⁇ is suspended in the air.
- the pores of the electrode having a porous structure are clogged with dust, and the diffusion of oxygen is hindered.
- the performance of the cathode decreases, and the battery performance decreases.
- the active metal mainly platinum in the air electrode
- a battery stack 910 in which unit cells are stacked is covered with a battery frame 920, and an air blower 930 is provided in the battery frame 920. Is installed, and air is supplied from the air inlet 940 to the air electrode side of the battery stack 910 through a predetermined pipe (not shown).
- An air purification filter 950 is provided at the air inlet 940. Since dust and the like contained in the air are captured by the filter 950, deterioration of the battery performance can be prevented, and the life of the battery can be extended.
- a fuel cell When a fuel cell is used in a portable device, its size may be limited in order to enhance portability.
- the size of the filter may be limited. Enlarging the filter lengthens the filter replacement period (lifetime). The portability of the equipment is impaired. On the other hand, when the size of the filter is reduced, the portability of the device is improved, but the life of the filter is shortened.
- the size of the filter 950 is considerably small, so that the replacement of the filter 950 is complicated or difficult. Therefore, when it is necessary to replace the filter 950, it is also conceivable to replace the fuel cell body not only with the filter at the same time. However, the replacement of the battery stack 910 or the air blower 930 which has not reached the end of its service life increases the cost, and reduces the merit of using a fuel cell instead of a lithium secondary battery or the like. [0012] In the portable fuel cell shown in Fig. 9, if the filter 950 having a sufficient size is used, the filter 950 does not need to be replaced until the life of the portable fuel cell reaches the end of its life. Is important, so a filter 950 that is large enough to impair the convenience of a portable device is very unlikely to be used in practice.
