Appl. No.:

13/825995

Inventors:

Jason B. Parsons - Manchester CT, US
Timothy W. Patterson - West Hartford CT, US
Michael D. Harrington - West Hartford CT, US
Christopher John Carnevale - Vernon CT, US

International Classification:

H01M 8/24
H01M 8/02

US Classification:

429460, 277628, 277312

Abstract:

An example seal assembly includes a first seal that is configured to be placed between a fuel cell manifold and a fuel cell stack. The first seal establishes a recessed area within a side of the first seal that faces the fuel cell stack. The fuel cell seal assembly further includes a second seal that is configured to be placed between the first seal and the fuel cell stack within the recessed area. An example method of sealing a fuel cell interface includes holding a first seal within a groove established within a manifold and holding a second seal within a recessed area established within the second seal. The method limits flow of a fuel cell fluid using a first seal and the second 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.
