  • Publication number: 20230178759
    Abstract: The present invention relates to a plate device (10) for an electrochemical fuel cell stack having stacked cells and a corresponding fuel cell device. The plate device is provided per each cell (20) for distributing and collecting a fluid across planar dimensions of a cell (20). A transition section (11) of the plate device (10) forms a flat shaped flow cross-section in a planar direction of the plate device (10) being in fluid communication between the fluid port (30) and the cell (20). Plate features for distributing or collecting a fluid to be transferred comprise at least one barrier element (16) being disposed within a fluid flow and having an elongated cross-section inclined to a flow direction of the fluid flow for locally throttling said fluid flow.
