Abstract: An exemplary fuel cell component includes a generally planar body having a total area defined by a length and width of the body. A first portion of the total area is occupied by a first fuel cell features that renders the first portion unusable for at least one fuel cell function. A second portion of the total area is occupied by a second fuel cell feature that renders the second portion unusable for the fuel cell function. A third portion of the total area is considered an active area of the component that is useful for the fuel cell function. An aspect ratio of the length to the width of the generally planar body is dependent on a dimension of the first portion and a dimension of the second portion.
