Bundling device and method thereof, bundling locker and fuel cell

Abstract

The invention relates to a bundling device, a bundling method, a bundling locker and a fuel cell. The bundling device is used for bundling a fuel cell stack and comprises a bundling element and a bundling locker, wherein the bundling element has a first end, a second end, and an extension main body, the extension main body of the bundling element is adapted to wrap a fuel cell stack, the bundling locker comprises at least one rolling piece and at least one limiting mechanism, the rolling piece is adapted to be rotatably disposed on the end plate of the fuel cell stack, and is connected to the first end and / or the second end of the bundling element, the rolling piece rolls the first end and / or the second end of the bundling element to tension the extension main body when the rolling piece is rotated relative to the end plate, the limiting mechanism is arranged to be used for limiting rotation of the rolling piece when the rolling piece tensions the extension main body, so that the extension main body is kept in a tightened state, and the bundling device is in a locked state.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a strapping device and its method, a strapping locker and a fuel cell. Background technique [0002] A fuel cell is a power generation device that converts chemical energy in fuel directly into electrical energy through electrochemical reactions. Due to the low voltage and output power that a single fuel cell (or fuel cell monomer) can provide, in practical applications, generally multiple fuel cells are stacked together to form a fuel cell that can provide high voltage and high power heap. Correspondingly, since the fuel cell stack of the fuel cell is formed by stacking a plurality of fuel cell cells, the fuel cell cells of the fuel cell stack must be firmly assembled to ensure the structural stability of the fuel cell stack. [0003] The fuel cell stacks of existing fuel cells are mostly fixed by screws to fix the multiple fuel cell cells of the fuel cell stack together. ...

AI Technical Summary

Problems solved by technology

However, this screw fixing direction requires the use of professional tools (such as wrenches) to firmly fix multiple fuel cell cells together

In particular, with the prolongation of the use time, the screw rod is rusted and cannot be disassembled, which makes it difficult to disassemble the multiple fuel cell cells of the fuel cell stack, which has a negative impact on the subsequent maintenance and maintenance of the fuel cell stack. great inconvenience

[0004] In addition, when using screws for fixing, in order to ensure the fixing of the fuel cell stack, it is often necessary to use multiple pairs of screws to achieve the purpose of fastening. And it will also lead to larger volume of fuel cell stack, complicated manufacturing process and higher manufacturing cost
