Description

  The present invention relates to a novel fuel cartridge and an electronic device.

In recent years, portable electronic devices such as telephones, personal computers, audio-visual devices, information terminal devices, etc. have become more compact and have higher performance, and accordingly, secondary batteries as power sources have also been reduced in size, weight and energy. Densification and the like are required. Secondary batteries need to be charged after a certain amount of power is consumed, and there are many problems with charging time and charging equipment. In addition, solid polymer fuel cells that have already been put to practical use in households, etc. in the field of fuel cells require a reformer to produce hydrogen gas as a fuel (however, a cylinder filled with hydrogen gas). It is difficult to apply as a power source for portable electronic devices because it has properties such as a high operating temperature.
On the other hand, the direct methanol fuel cell is basically based on the power supply by directly supplying the methanol aqueous solution as fuel without reforming or gasifying it. Therefore, since a reformer is not required, it is easy to reduce the size and weight, and has a feature such as a low operating temperature, and is expected as a power source for portable electronic devices.

  In direct methanol fuel cells, the methanol aqueous solution that is fuel is consumed as the battery is driven, so it is necessary to replenish the methanol aqueous solution according to the amount of consumption. It becomes possible to make it. As disclosed in Patent Document 1 and Patent Document 3, the fuel supply method in the direct methanol fuel cell is disclosed in the case of supplying from a fuel tank directly connected to the direct methanol fuel cell main body and in Patent Document 2. As described above, the battery main body does not have a fuel tank and the fuel cartridge is directly incorporated into the fuel cell main body for use. Even in the case of having the former fuel tank, the fuel tank can be replenished with fuel by using a cartridge system. As described above, in the direct methanol fuel cell, it is expected that the fuel replenishment method can be simplified by adopting the cartridge replenishment method, and the spread as a power source for portable electronic devices can be further accelerated.

  By the way, methanol used as fuel is a deleterious substance stipulated in the Poisonous and Deleterious Substances Control Law, and is further designated as a fourth class alcohol in the dangerous goods classification by the Fire Service Law. Therefore, when handling the cartridge, it is necessary to prevent the aqueous methanol solution from adhering to the human body and surrounding contamination.

  However, none of the above-described patent documents discloses a structure in which a fuel cartridge is integrally coupled to a direct methanol fuel cell when a methanol aqueous solution as a fuel is replenished from the fuel cartridge.

  An object of the present invention is to prevent a methanol aqueous solution from leaking when a methanol aqueous solution, which is a fuel, is replenished from a fuel cartridge in a direct methanol fuel cell. It is to provide a cartridge and an electronic device.

  The present invention is connected to a fuel cartridge housing serving as a fuel chamber for storing fuel, and a supply port for supplying the fuel in the fuel cell to a supply port for supplying the fuel to the fuel cell. Connecting means, and the connecting means is formed in a concave or convex shape with respect to the casing.

The present invention also includes a housing having a fuel cell built therein and an electronic device, and a fuel cartridge having a supply port that communicates with the fuel chamber for storing fuel for the fuel cell and supplies the fuel to the fuel cell. Storage means, and a connection means provided in the storage means and connected to the supply port in communication with a supply port for supplying the fuel to the fuel cell, the connection means being recessed in the storage means. Alternatively, the electronic device is formed in a convex shape.
The connection means includes a flow path valve that is pressed by an elastic body to prevent leakage of the fuel by a stopper, and a pressing member that is provided on the stopper side of the flow path valve and presses the flow path valve toward the fuel storage side. And a structure in which the fuel is caused to flow out of the supply port and to flow in from the supply port by pressing the pressing member.

Furthermore, the present invention includes a housing having an electronic device in which a fuel cell is incorporated, a fuel cartridge housing serving as a fuel chamber for storing fuel for the fuel cell, and a supply port for supplying the fuel to the fuel cell. Storage means for storing a fuel cartridge; and connection means provided in the storage means for replenishing the fuel cell with a supply port for replenishing the fuel; and connecting means for detachably connecting the supply port to each other. In the electronic apparatus, the fuel cartridge housing and the storage means are each formed in a concave shape or a convex shape, and the connecting means has a structure that fits into the concave shape and the convex shape.
It is preferable that the connection means has a connection structure that prevents the fuel from leaking before being connected to each other and that opens the fuel flow path by pressing during connection.

  The stopper of at least one of the storage means and the fuel cartridge is made of a rubber member, the supply port and the supply port are pressed into each other, and the other outer peripheral surface is in contact with one inner peripheral surface and the fuel The insertion means are inserted in close contact with each other so as not to leak, the storage means has an elastic member that presses the supply port of the fuel cartridge against the supply port, and further, the fuel contains a methanol solution. The liquid fuel is preferably included.

The present invention has an anode electrode on one surface and a cathode electrode on the other surface via an electrolyte membrane, and generates electricity by supplying a methanol solution to the anode electrode and an oxidizing gas to the cathode electrode. It is preferable for application to a direct methanol fuel cell.
According to the present inventors, the largest cause of methanol solution leakage when handling the methanol solution supply cartridge is insufficient connection between the supply port of the methanol solution supply cartridge and the replenishment port of the direct methanol fuel cell. I found out. The present invention provides a connecting device that does not supply a methanol aqueous solution unless the supply port of the methanol aqueous solution supply cartridge and the replenishment port of the direct methanol fuel cell are securely connected. It is possible to prevent the methanol aqueous solution from leaking by attaching the two to the supply port and the supply port. Furthermore, in the present invention, the connecting device is formed in a concave shape or a convex shape with respect to the fuel cartridge housing and the inside of the storage means, and has a structure that fits to each other by the concave shape and the convex shape. It can be accommodated within the outer dimensions of the aqueous solution supply cartridge, and the dead space caused by attaching the connecting device is eliminated.

  The present invention provides a connection device that connects a supply port of a methanol aqueous solution supply cartridge and a replenishment port of a methanol fuel cell when the supply port and the replenishment port are not connected or connected so as not to leak a methanol aqueous solution of fuel. When the flow rate is insufficient, the flow channel is closed, and the flow channel is opened only when the supply port and the supply port are correctly connected. Such a function controls the opening and closing of the flow path between the supply port and the supply port by pressing when the supply port of the cartridge for supplying methanol aqueous solution and the fuel supply port of the direct methanol fuel cell are connected. Here, in order to maintain the pressure for opening the flow path at the time of connection, the connection tool has a lock mechanism for maintaining the connection and a mechanism such as fitting with a certain stress or more.

As described above, the connecting device of the present invention is composed of a plug portion and a socket portion, and has a valve that opens and closes due to stress in the flow path of each component. In this state, an aqueous methanol solution can be supplied.
By the way, by attaching the connector to the supply port of the methanol aqueous solution supply cartridge and the fuel cell replenishment port, the connection instrument part protrudes from the dimensions of the methanol aqueous solution supply cartridge and the fuel cell part on the electronic device casing side. In this case, a gap (dead space) is generated between the methanol aqueous solution supply cartridge and the fuel cell unit on the electronic device casing side. In portable electronic devices, miniaturization is an essential requirement for portability, and it is necessary to eliminate the dead space caused by attaching the connecting device. In this shape, a space for storing the connection device is provided.

Further, another preferred mechanism for achieving the present invention is a methanol aqueous solution supply cartridge, wherein the supply port of the methanol aqueous solution supply cartridge and the fuel supply port of the direct methanol fuel cell are connected by a spring pressure. Moreover, it is preferable that it is a shape which can accommodate a connection instrument in the outer dimension of the cartridge for methanol aqueous solution supply. In order to maintain the pressure for opening the flow path at the time of connection of the connection tool used here, it is a method by the pressing force of the spring. By this method, the cartridge for supplying methanol aqueous solution can be easily detached.
As a method of maintaining the connection of the connection device, the lock mechanism or the method of fitting with a certain stress or more is to lock the lock mechanism while holding the methanol aqueous solution supply cartridge when connecting / disconnecting the connection devices (plug part and socket part). It requires unlocking or pushing and pulling arm strength. However, in the method of connecting by the stress by the spring described later, the arm force for locking and unlocking the lock mechanism, or pushing and pulling is not required. Further, by providing a space in the shape of the methanol aqueous solution supply cartridge in which the connection fitting can be stored, it is possible to eliminate a dead space caused by attaching the connection tool.

In the present invention, the housing for the methanol aqueous solution supply can be more easily assembled by providing a housing guide as a housing means in accordance with the shape of the cartridge for methanol aqueous solution supply in the casing of the electronic device.
The material of the cartridge body and supply port for methanol solution supply according to the present invention, the fuel supply port of the direct methanol fuel cell and the fuel tank, the connecting device, etc. are made of metal, plastics, productivity, cost, recyclability Etc. are selected as appropriate. In addition, the diameter of the supply port of the methanol solution supply cartridge, the direct methanol fuel, and the fuel replenishment port of the fuel tank are determined by the capacity of the methanol solution supply cartridge, the capacity and supply speed of the fuel tank in the direct methanol fuel cell, etc. Decided in consideration.
In order to facilitate the supply of the methanol solution, the methanol solution supply cartridge and the direct methanol fuel cell or the built-in fuel tank may have an auxiliary mechanism such as a pressure adjustment valve for adjusting the pressure. good.

  According to the present invention, in a direct methanol fuel cell, when a methanol aqueous solution as a fuel is replenished from a fuel cartridge, a fuel that prevents a methanol aqueous solution from leaking, can be detachably attached, and eliminates a dead space. A cartridge and an electronic device can be provided.
