Abstract

The invention relates to the technical field of fuel cells, and discloses a pressurized assembly, a fuel cell stack and its first end plate assembly, a pressurized frame, an assembly method and a vehicle. A pressurized assembly, the pressurized assembly includes a support rod and a connecting plate, wherein the connecting plate includes a connecting portion for being fixedly installed on the side plate surface of the first end plate of the fuel cell stack for facing away from the fuel cell stack, Wherein, the support rod is arranged on the connecting plate, and a pressurized body is arranged on the support rod, and the pressurized body includes an end plate for pressing the fuel cell stack and facing toward the fuel cell stack. The compressive outer surface of one side deck. After the pressurized component is applied to the fuel cell stack, it can apply sufficient uniform compression to the fuel cell stack and is easy to assemble.

Description

technical field [0001] The present invention relates to the technical field of fuel cells, in particular to a pressurized assembly for a fuel cell stack, a fuel cell stack, a fuel cell stack first end plate assembly, a fuel cell stack pressurized frame, a fuel cell stack A fuel cell stack assembly method and a vehicle. Background technique [0002] A proton exchange membrane (PEM) fuel cell uses a membrane electrode assembly (MEA), which includes a polymer electrolyte membrane, an anode disposed on one side of the electrolyte membrane, and a cathode disposed on the other side of the electrolyte membrane. A membrane electrode assembly is sandwiched between a pair of separators to form a fuel cell that generates electricity. And a plurality of fuel cells are stacked together between a pair of end plates in a direction from one end plate toward the other end plate to form a fuel cell stack. [0003] In order to make a plurality of fuel cells have a certain stacking pressure i...
