1. A fluid distribution assembly for use in a fuel cell, comprising:

  • a separator having a major surface;

    a boundary element disposed on the major surface; and

    a flow field having channels formed on the major surface of the separator plate, the channels and the boundary elements defining a cross-sectional configuration that provides a water accumulation zone along the length of the channels;

    the channel has a sidewall defining a width and a depth, an acute angle being defined at an interface between the sidewall and the boundary element, the width continuously linearly decreasing along the depth of the channel in a direction generally away from the boundary element.
