Fuel Cell Devices

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 membrane electrode assembly may include at least one membrane for fuel cell reactions, and the two gas diffusion layers may be respectively coupled with the two opposite sides of the membrane electrode assembly. The fluid flow plate assembly is coupled with the membrane electrode assembly at a first side of the two opposite sides of the membrane electrode assembly. At least one of the membrane electrode assembly, the two gas diffusion layers, the two current collectors, and the two sealing members has a non-planar surface prior to an assembly of the membrane electrode assembly, the two gas diffusion layers, the two current collectors, and the two sealing members, and the non-planar surface is at least partially flattened when the assembly occurs.
