Problems solved by technology

[0007] However, in the liquid fuel direct supply type fuel cell of the said document, since the container 2 is filled with the porous material 7, the amount of the liquid fuel 1 that can be accommodated in the container 2 is small, and it is difficult to realize the length of the machine. time driven questions
In addition, due to the use of the porous material 7, impurities such as dust will be mixed in the liquid fuel 1, which will reduce the electrolyte performance of the fuel cell.

Embodiment Construction

[0042] A fuel cell liquid fuel storage container and a fuel cell system which are embodiments of the present invention will be described below with reference to the drawings. Furthermore, the fuel cell system is a system including the liquid fuel storage container for the fuel cell. In addition, in each figure, the same code|symbol is used for the same component.

[0043] First, refer to Figure 11 , the fuel cell system 190 provided with the fuel cell liquid fuel storage container 101 according to the embodiment will be described.

[0044] The fuel cell system 190 includes a fuel storage container 101 , which will be described in detail later, and a fuel cell main body 180 that receives a supply of fuel from the fuel storage container 101 and generates electricity. The liquid fuel supplied from the main body 180 contains an aqueous methanol solution at a concentration of about 10%. In addition, in order to supply fuel from the fuel storage container 101 to the fuel cell ma...

Abstract

The object of the present invention is to provide a liquid fuel storage container for fuel cell capable of storing liquid fuel to be supplied to a liquid-fuel direct-supply type fuel cell and stably supplying liquid fuel for a long time, and also provide a fuel-cell system. The present invention employs a fuel-supplying pipe ( 120 ) extending within a tank member ( 110 ) for supplying liquid fuel ( 185 ) and having flexibility, and provides a weight member ( 122 ) at a portion near a suction port ( 121 ) for liquid fuel on the fuel-supplying pipe. Accordingly, the suction port can move to a portion where the liquid fuel exists, anytime, and can be kept immersed in the liquid fuel. This enables stably supplying fuel even when the fuel cell is mounted on a portable electronic apparatus.

Description

technical field [0001] The present invention relates to a liquid fuel storage container for a fuel cell containing liquid fuel supplied to a liquid fuel direct supply type fuel cell, and a fuel cell system including the liquid fuel storage container. Background technique [0002] Conventionally, secondary batteries such as nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries have been used as power sources for portable devices such as mobile phones and portable computers. These devices are often used in a state where the power supply is always connected, and there is a limit to prolonging the continuous use time of the portable device using the secondary battery. [0003] In response to this, attempts have been made to use fuel cells as power sources for portable devices. Unlike solid polymer fuel cells, which use hydrogen as fuel, in which the water content of the electrolyte membrane is complicated to control, liquid fuel direct supply type f...
