Definitions
- the present invention relates to a flow rate adjusting filter installed in a fuel container for a fuel cell and a fuel container for a fuel cell provided with the flow rate adjusting filter.
- Fuel cells which have a low operating temperature and can be expected to be smaller, are currently used in a variety of applications, such as power supplies for mobile devices that can extend the continuous operating time of notebook computers and mobile phones. Development is underway. There are various types of fuel cells, and there are several types of fuels used. For example, in a direct methanol fuel cell (DMFC) that directly supplies methanol, a system that uses a mixed solution of methanol and pure water as fuel, or a system that uses pure methanol by reusing water that is the waste liquid of a fuel cell (For example, see JP-A-2003-297401).
- DMFC direct methanol fuel cell
- a fuel in which nitrogen or dimethyl ether (hereinafter, DME) is mixed as a propellant into an aqueous methanol solution is known (see, for example, JP-A-6-310166). Gazette).
- direct DME fuel cells use a mixture of liquefied DME and water, or a mixture of liquefied DME and water with methanol as fuel, and use hydrogen produced from DME as fuel.
- a DME reforming method for supplying batteries is also under consideration (for example, see Japanese Patent Application Laid-Open No. 2002-505511, “R & D on polymer electrolyte fuel cells” (PEFC) Research Report ”2001 Annual Report Published by the New Energy and Industrial Technology Development Organization, March 2002, [Retrieved March 1, 2004], Internet ⁇ URL; http Go to ⁇ www..nedo.go.jp>).
- DME has attracted attention because it is a clean liquid fuel free of sulfur, heavy metals and aromatics, has excellent ignitability and combustibility, and is relatively easy to transport and store.
- SOFC small solid oxide fuel cells
- Liquefaction A system that uses a mixture of DME and water as a fuel is being studied (for example, the Fundamental Technology Research Promotion Project “Research on micro solid oxide fuel cells using DME and LPG as fuel”) Results of FY2002 Report issued by the New Energy and Industrial Technology Development Organization, published on March 2003, [Searched March 1, 2004], Internet URL: http://www.nedo.go.jp> ).
- a fuel container for supplying fuel cell fuel to the fuel cell is also being studied.
- This fuel container for a fuel cell is small and lightweight, and is preferably made of resin in order to confirm the remaining amount of the contents.
- DME-resistant resin containers have also been studied and filed by the present applicant (see, for example, Japanese Patent Application Laid-Open No. 2003-176899, Japanese Patent Application No. 2003-270600, Japanese Patent Application No. 2003-297049).
- the fuel supply flow rate needs to be very small. It must be able to supply.
- the fuel consumption of small fuel cells is as small as several m1 to several tens of m1 in several hours, and the container body has a discharge characteristic that keeps the amount of ejected contents small, which simplifies the mechanism on the fuel cell side. It is important in planning.
- valve diameter and the outlet diameter In general aerosol containers, it is necessary to reduce the amount of ejected contents by reducing the valve diameter and the outlet diameter.However, the valve diameter and the outlet diameter may be reduced to 0.3 mm. This is the limit that can be achieved. In this case, the entire contents are ejected in a few minutes, which is not suitable for a fuel container for a fuel cell. In addition, there is a problem that the amount of outflow per hour is extremely small in the case of spontaneous ejection due to the self-weight of the contents, so that usable devices are limited.
- a container that requires a strictly stable ejection volume usually requires the installation of a liquid amount adjustment mechanism.However, since a fuel container for a fuel cell is required to be small and lightweight, a large liquid amount adjustment mechanism is required. Can not be used.
- the present inventors dispose a filter for adjusting a flow rate such as a flow rate adjustment filter used for adjusting a flame of a gas lighter in a fuel container body for a fuel cell.
- a filter for adjusting a flow rate such as a flow rate adjustment filter used for adjusting a flame of a gas lighter in a fuel container body for a fuel cell.
- the liquid contained contains methanol
- the urethane foam-based, rubber sponge-based, and non-woven-based filters used in gas lighters are eroded or swollen by this methanol. A change in flow rate occurs and there is a problem in durability.
- the filler will be corroded, and if non-woven fabric is used for the filter, the binder, which is the binder of the non-woven fabric, will be attacked by the DME, and lint will be generated. May cause nozzle clogging.
- An object of the present invention is to provide a flow rate control filter that does not elute impurities and a fuel container for a fuel cell provided with the flow rate control filter.
