Beständiger niedriger Übergangswiderstand zwischen bipolarer Platte und Diffusionsmedium

摘要

A fuel cell includes a first polymer electrolyte membrane (PEM) and a plate having a series of flow channels formed in a first surface. A first diffusion medium is disposed between the first PEM and the plate and is in direct contact with the first surface. A first sealing layer secures the direct contact between the first diffusion media and the plate and seals the first surface.
