Abstract
A fuel cell system may include a fuel cell stack having a header and active area in fluid communication with the header. The fuel cell system may also include a wedge disposed within the header and configured to alter the cross-sectional area of the header along the length of the stack such that, during operation of the stack, a flow velocity of gas through the active area is generally constant.
