  • Method of making a fuel cell component having an interdigitated flow field configuration
    Patent number: 9755250
    Abstract: According to an illustrative embodiment, a method of making a fuel cell component includes removing material from a first plurality of locations along at least one surface on a plate to simultaneously establish a plurality of first channels on the surface. Each first channel has a length between a first end near a first edge of the surface and a second end spaced from a second, opposite edge of the surface. Material is also removed from a second plurality of locations along the surface to simultaneously establish a plurality of second channels on the surface. Each second channel has a length beginning at a first end spaced from the first edge and a second end near the second edge. Material is also removed from the surface near the first ends of at least some of the first channels to simultaneously establish an inlet portion for directing a fluid into the corresponding first channels.
