Abstract

A fuel distributor assembly for a fuel cell stack that includes an inner shell positioned within an outer shell. The outer shell is curved to define a central longitudinal chamber, a first longitudinal edge and a second longitudinal edge. The outer shell also has an inner wall surface and an outer wall surface. The first longitudinal edge and the second longitudinal edge in combination define a longitudinal slot. The first longitudinal edge is bent inwardly towards the longitudinal chamber to form a longitudinal lip. The inner shell includes a plurality of ribs extending outwardly and contacting the inner wall surface of the outer shell. The inner shell, the outer shell, the lip, and the ribs define a plurality of flow channels. The inner shell has a length along which a plurality of apertures are positioned in a partial helical pattern. A method of forming the fuel distributor is also provided.
