Embodiment Construction

[0049] The exemplary embodiments described herein are applicable to fuel cell technology, and may provide a plate member for a cell stack. For example, bipolar plates can be provided that can simplify the assembly process of proton exchange membrane fuel cell (PEMFC) stacks, improve stack performance, and reduce manufacturing costs.

[0050] figure 1 is a front view of a plate member for a battery stack in an exemplary embodiment. In the exemplary embodiment, plate member 100 includes two alignment features 102 and 104 and channel sheet 110 . In an exemplary embodiment, the channel sheet 110 includes at least one peak and one valley in the body of the sheet and is in the form of a corrugated sheet 110 . The corrugated sheet 110 is coupled to a first alignment feature 102 at a first end or edge 112 of the corrugated sheet 110 and to a second alignment feature 104 at a second end or edge 114 of the corrugated sheet 110 . Accordingly, the corrugated sheet 110 is disposed betwe...

Abstract

A plate member for a battery stack, a battery stack assembly, a method of forming a plate member of a battery stack, and a method of assembling a battery stack may be provided. The plate member includes a channel piece including at least one peak and one valley for forming a fluid flow channel. two alignment components, each alignment component comprising a main body and one or more alignment members, the main body having a through hole disposed within the main body; and wherein the alignment components are capable of aligning the The alignment member is aligned to another corresponding alignment member; and wherein the channel sheet is disposed between the two alignment members.

Description

technical field [0001] The present disclosure relates broadly to plate members for battery stacks and methods of forming plate members for battery stacks. Background technique [0002] In current technology, fuel cell components are increasingly being integrated to simplify the stack assembly process and reduce costs. For example, a typical membrane electrode assembly (MEA) with five layers is commonly used. This five-layer MEA includes a layer of proton exchange membrane (PEM) sandwiched or disposed between two layers of dispersion medium, with a layer of catalyst located in the two interfaces between the PEM and the dispersion medium. This arrangement integrates the membrane, electrodes, and diffusion media, which simplifies the MEA stack assembly. [0003] However, there are other advances regarding other important components of the stack that serve as bipolar plates. [0004] In the PEM fuel cell industry, the materials used have improved significantly. Conventional ...
