Embodiment

[0034] This embodiment provides a fuel cell, which can be used as a new energy cell to provide energy to the outside world.

[0035] Specifically, please also refer to Figure 1-3 , the fuel cell includes a stack 5 , a first end plate 2 , a second end plate 8 , a first insulating plate 3 , a second insulating plate 7 , a positive plate 4 , a negative plate 6 and a fastening strap 1 . The first end plate 2, the first insulating plate 3, the positive plate 4, the stack 5, the negative plate 6, the second insulating plate 7 and the second end plate 8 are stacked in sequence to form a whole, and the whole is fastened by a cable tie 1 Fasten.

[0036] In this embodiment, the first end plate 2 and the second end plate 8 are provided with grooves for installing the fastening tie 1 . The fastening tie 1 is installed in the groove, which can prevent the fastening tie 1 from sliding or dislocation, so that the fastening effect is better.

[0037] Wherein, electric stack 5 is formed b...

Abstract

The invention provides a fuel cell. The fuel cell comprises an electric pile, a first end plate, a second end plate, a first insulating plate, a second insulating plate, a positive plate, a negative plate and a fastening tie, wherein an entirety formed by sequentially overlaying the first end plate, the first insulating plate, the positive plate, the electric pile, the negative plate, the second insulating plate and the second end plate is fastened by the fastening tie, and a groove used for mounting the fastening tie is formed in each of the first end plate and the second end plate respectively. The fuel cell provided by the invention has the advantages that the best fuel cell stack fastened with a load can be reliably applied in the laminating direction of the fuel cell under the condition of a small and light structure; besides, the fuel cell stack applied to an external load of the fuel cell can be borne reliably with a simple structure and few components; and the fastening tie islow in cost and convenient and efficient in mounting and dismounting, and tightness degree of the fastening tie can be easily adjusted.

Description

technical field [0001] The invention relates to the field of batteries, in particular to fuel cells. Background technique [0002] Energy is the foundation of economic development, without the development of the energy industry there would be no modern civilization. Human beings have been making unremitting efforts to use energy more efficiently. There have been many revolutionary changes in the way of energy utilization in history, from the original steam engine to steam turbine, high-pressure steam turbine, internal combustion engine, and gas turbine. Every change in the way of energy utilization has greatly promoted the development of modern civilization. A fuel cell is a device that converts chemical energy stored in fuel and oxidant directly into electrical energy. When a fuel cell is continuously supplied with fuel and oxidant from the outside, it can generate electricity continuously. [0003] A fuel cell has a unit cell (power generation unit) in which an electrol...
