摘要： An illustrative example fuel cell component includes a plate with a plurality of flow channels in at least one side of the plate. Each of the flow channels has a length between an inlet and an outlet. Each of the flow channels has a width and a depth, which are transverse to the length. At least some of the flow channels include a portion near the inlet and the width or the depth of the portion is greater than the width or depth along a majority of the length of those flow channels.

摘要： An illustrative example embodiment of a fuel cell component includes a graphite substrate, a polytetrafluoroethylene (PTFE) layer adjacent a portion of the graphite substrate, and a plurality of segments of acrylic adhesive between the portion of the graphite substrate and the PTFE layer. The acrylic adhesive secures the PTFE layer to the portion of the graphite substrate. There is spacing between adjacent ones of the segments.
