Non-channeled and anisotropic flow field for distribution sections in fuel cells

Abstract

A fuel cell has an active area and a distribution area. The distribution area can be in communication with and disposed substantially adjacent to the active area. The active area can include a non-channeled material exhibiting anisotropic flow. In certain circumstances, the non-channeled material exhibiting anisotropic flow can include expanded metal sheet. The expanded metal sheet can achieve even distribution to throughout the active area without the use of conventional channels.
