Embodiment 1

[0021] A fuel container for a fuel cell, such as figure 1 As shown, it includes 4 fuel tanks and 1 fuel tank connector; the bottom of the fuel tank is provided with a fuel tank connector interface, and the fuel tank connector is a container with 7 interfaces, which is set in the upper part of the fuel tank There are atmospheric communication holes; the four fuel tanks are serially sealed and detachable connected through three fuel tank connectors, at least one of the four fuel tanks is connected to the fuel cell stack fuel inlet through a fuel tank connector Pass. The volume of the 4 fuel tanks is 250-2000mL, using the same joint specification, the volumes can be the same or different. The fuel tank is connected to a fuel tank connector through a quick-plug connector, so fuel filling and replacement are quick and easy. The quick plug interface is airtight when no fuel tank is inserted.

Embodiment 2

[0023] A fuel container for a fuel cell, such as figure 2 As shown, it includes 4 fuel tanks and 3 fuel tank connectors; the bottom of the fuel tank is provided with a fuel tank connector interface, and the fuel tank connector is a container with 2 interfaces, which is set in the upper middle of the fuel tank There are atmospheric communication holes; the four fuel tanks are serially sealed and detachable connected through three fuel tank connectors, at least one of the four fuel tanks is connected to the fuel cell stack fuel inlet through a fuel tank connector Pass. The volume of the 4 fuel tanks is 250-2000mL, and the volumes can be the same or different. The fuel tank connector is a flexible connection, and the fuel tanks can be arranged in a "star shape", "tooth shape" or other various forms according to the fuel storage space.

Embodiment 3

[0025] A fuel container for a fuel cell, such as image 3 As shown, it includes 4 fuel tanks and 3 fuel tank connectors; the bottom of the fuel tank is provided with a fuel tank connector interface, and the fuel tank connector is a container with 2 interfaces, in each fuel tank The upper part is provided with an atmospheric communication hole, and there is a waterproof and breathable film barrier between the atmospheric communication hole and the outside world; the four fuel tanks are sealed and bonded in series through three fuel tank connectors, and two of the four fuel tanks Each of them communicates with the fuel cell stack fuel inlet through a fuel tank connector. The volume of the 4 fuel tanks is 250-2000mL, and the volumes can be the same or different. The fuel tank connector is a flexible connection, and the fuel tanks can be arranged in a "star shape", "tooth shape" or other various forms according to the fuel storage space.

Abstract

A fuel container for a fuel cell, comprising N fuel tanks and N fuel tank connectors, where N is a natural number greater than or equal to 2; the bottom of the fuel tank is provided with a fuel tank connector interface, and the fuel tank connector has two A container with two interfaces, an atmosphere communication hole is arranged in the upper part of the fuel tank; the N fuel tanks are serially sealed and detachably connected through N-1 fuel tank connectors, and at least one of the N fuel tanks is One communicates with the fuel cell stack fuel inlet through a fuel tank connector. Compared with the prior art, the fuel container of the present invention is convenient for adding fuel, realizes fast fuel filling in a bomb bay type, and can complete fuel adding by replacing a single fuel tank. And it can realize adding fuel without shutting down for a long time. It is convenient to increase and decrease the capacity, and the carrying amount of fuel can be easily changed at any time, and different amounts of fuel bottles can be carried according to the expected mission time. Save the inconvenience of using a unified large fuel tank.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a fuel container for a fuel cell, which is used for a fuel cell carrying liquid fuel. Background technique [0002] Direct alcohol fuel cells have been widely used as portable mobile power sources, and portable fuel cell devices require fuel tanks that are easy to carry and replace. The existing fuel tank has fixed shape, large volume, and complex interface, which cannot meet the complex and changeable application requirements of portable fuel cell mobile power in the field. Therefore, this patent introduces a portable liquid-feed fuel cell that requires a portable fuel tank, which is convenient for capacity expansion and contraction according to tasks, is light and safe, can be installed and disassembled quickly, and can be built-in or externally connected. Contents of the invention [0003] Aiming at the shortcomings of existing fuel tanks and liquid storage t...
