Problems solved by technology

At the same time, there are many components in the stack package, the process is complicated, the requirements for assembly and subsequent maintenance are high, and the cost of production and subsequent maintenance will be relatively high.
The fuel cell stack packaging structure of Kunshan Fursai Energy Co., Ltd. (China ZL201220005574.4), although there are few packaging parts, it also separates the fuel cell packaging assembly from the assembly of the stack body. From the perspective of installation technology , is still slightly complicated

Abstract

The invention discloses a fuel cell stack packaging structure, which belongs to the technical field of fuel cells. The packaging structure of the fuel cell stack includes a hollow cubic structure without a cover assembled by a packaging fixing plate and a cylinder. A packaging flange is provided on the inside of the top edge of the cylinder, and a guide plate is provided on the inside of the cylinder. The two ends of the guide plate are respectively connected to the The package fixing plate is connected with the package flange. There is a groove on the surface of the package flange facing the inside of the cylinder. The groove can place the clip in the groove. There is also a package pressure plate in this structure, and the package pressure plate is in operation. The lower edge is arranged below the clamping strip, and a clamping strip baffle is arranged between the packaging pressure plate and the packaging flange to fix the clamping strip. The assembly and disassembly process of the electric stack packaging structure described in the present invention is simple and easy to operate, and can quickly complete the assembly and disassembly of fuel cell electric stack units.

Description

technical field [0001] The invention relates to a fuel cell stack packaging structure, in particular to a fuel cell stack packaging structure that can be quickly assembled and disassembled, and belongs to the technical field of fuel cells. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) (hereinafter referred to as fuel cell) relies on electrochemical reactions to directly convert chemical energy in fuel gas (such as hydrogen) into electrical energy. In recent years, as countries around the world pay more and more attention to environmental pollution control, fuel cell power generation has the characteristics of high energy conversion efficiency, green and pollution-free exhaust gas, and safety, and has been paid more and more attention to. Application scenarios such as power generation, aviation (sky) device power generation, underwater equipment power generation, marine power generation, vehicle-mounted generators, and field emergency power generati...
