Encapsulation method of galvanic pile module of fuel cell

Abstract

The invention relates to an encapsulation method of a galvanic pile module of a fuel cell, which comprises the following steps that: firstly, an integral galvanic pile is arranged in an encapsulation box from the rear end, eight fixed blocks on the galvanic pile are connected by bolts and software damping linings are arranged between fixed pins and the encapsulation box; secondly, on a back cover plate, a 1 millimeter white tetrafluoro pad is horizontally placed on a hydrogen joint, a 2 millimeter silica gel gasket is horizontally placed on a stainless steel joint, the white tetrafluoro pad and the silica gel gasket are stuck by fast-curing adhesives, and after curing, the back cover plate and the encapsulation box are fixed by eight M5-10 flange face screws and a red gasket; and finally, the galvanic pile module is arranged vertically, the back cover plate is downwards, and a front cover plate and the encapsulation box are fixed by the eight M5-10 flange face screws and the red gasket, so that the encapsulation of a galvanic pile module structure is completed. In the encapsulation method, components and parts in the integrated structure of the galvanic pile module of the fuel cell are integrated step by step; and the design that the fixed pins of the galvanic pile are connected with the encapsulation box is adopted, so that the galvanic pile module of the fuel cell has the functions of water prevention, dust prevention, seismic resistance, electric insulation, hydrogen safety protection, heat insulation and the like.

Description

technical field [0001] The invention relates to a packaging method for a proton exchange membrane fuel cell, in particular to an integrated packaging method for a stack module of a proton exchange membrane fuel cell. Background technique [0002] In today's global energy shortage and high oil prices, it is imperative to find new energy as a substitute for fossil fuels. Fuel cells are considered to be the fourth-generation power generation technology after hydropower, thermal power and atomic power generation. It directly converts the chemical energy of oxidants and reductants into electrical energy through electrocatalytic reactions. It is an efficient, safe, clean and flexible new type of power generation technology. power generation technology. Among them, the proton exchange membrane fuel cell has a wide range of application prospects in ground power stations, electric vehicles and portable power sources due to its remarkable advantages such as high efficiency, high ener...

Problems solved by technology

Although this packaging device can function as waterproof and dustproof, hydrogen leakage safety protection, etc., the operation of the exhaust fan and blower requires additional power consumption, and the ventilation pipe is equipped with filtering equipment, which is easily damaged by rainwater.

[0013] For the above-mentioned various fuel cell stack module packaging devices and methods, all specific requirements such as waterproof and dustproof, shock resistance, insulation, heat insulation, and hydrogen leakage protection of the integrated design have not been fully considered.
