Title: Fuel cell seal

Abstract

An example fuel cell seal assembly includes a seal configured to restrict flow of a fuel cell fluid through at least one of an outer lateral edge of a first gas diffusion layer, an outer lateral edge of a membrane electrode assembly, and an outer lateral edge of a second gas diffusion layer. The outer lateral edge of the first gas diffusion layer is laterally spaced from the outer lateral edge of the second gas diffusion layer. An example method of sealing a fuel cell interface includes limiting flow of a fuel cell fluid using a seal configured to restrict flow through an outwardly facing edge of at least one of a first gas diffusion layer and an outwardly facing edge of a second gas diffusion layer. The outwardly facing edge of the first gas diffusion layer is spaced from the outwardly facing edge of the second gas diffusion layer.
