Improvement on the uniformity of fluid flow rate for interconnecting plate for planar solid oxide fuel cell

摘要

A flat connecting plate designed for solid oxide fuel cell to improve the uniformity of fluid flow rate comprising a series of parallel ribs and grooves formed by the spaces between the ribs, the lengths of the ribs vary in accordance with the variation of the edge at proximity of fluid inlets, the widths of the grooves reduced in sequence from edges to center of the connecting plate, a series of diamond blocks placed at proximity of fluid outlet symmetrical to the center line of the connecting plate, and/or a series of fluid guide plates formed in parallel at the middle of two fluid inlets.
