Separator Plate Channel Layout for Uniform Fuel Cell Flow

The patent applies local quality by varying the number of second channels connected to each first channel in the distribution area based on local requirements. Specifically, first channels with longer lengths are connected to fewer second channels, while first channels with shorter lengths are connected to more second channels. This local adaptation of connection multiplicity compensates for the length differences and equalizes mass flows across all channels, thereby maintaining high operating efficiency while achieving wide fluid distribution.

The patent employs asymmetry by creating an asymmetric connection pattern between the distribution area and flow field channels. Instead of uniform connection multiplicity, the design intentionally creates asymmetric connections where the number of connected second channels varies systematically based on the length of each first channel. This asymmetric design compensates for the inherent asymmetry in channel lengths, achieving uniform mass flow distribution while maintaining broad fluid reach coverage across the flow field.
