Fuel cell system and fuel cell module thereof

Abstract

A fuel cell module may include a membrane electrode assembly, two gas diffusion layers, two current collectors, two sealing members, and a fluid flow plate assembly. The two gas diffusion layers are coupled with opposite sides of the membrane electrode assembly. The current collectors are coupled with the gas diffusion layers and the sealing members. The fluid flow plate assembly is coupled with the membrane electrode assembly at a first side thereof and has a channel. At least one of the membrane electrode assembly, the gas diffusion layers, the current collectors, and the sealing members has a non-planar surface at least partially flattened when the assembly occurs.

Description

technical field [0001] The invention relates to a fuel cell device, in particular to a fuel cell module capable of strengthening the contact force between internal components. Background technique [0002] The conventional flow field plate refers to a structure that can be used to carry, transmit, divide and / or distribute one or more fluids. The fluid referred to here is a general term in a broad sense, which can be any A substance that flows from one location to another. For example, the aforementioned fluid may include air, gas, liquid, or viscous fluid, etc., and the substance may flow or move from any position in the space to another position. [0003] Conventional flow field plates can be used, for example, in fuel cells to transport, guide and / or distribute one or more fuels, liquid or gaseous substances that can be used to generate electricity. figure 1 A conventional fuel cell device is disclosed, such as a single cell structure 400 of a proton exchange membrane fu...

AI Technical Summary

Problems solved by technology

[0004] Conventional fuel cells in some cases have poor contact between electrodes or other components due to insufficient contact force between internal components, which will lead to poor overall performance of the fuel cell
