Fuel Cell Bipolar Plate Coolant Flow Path Design

The patent applies local quality by varying the coolant flow path configuration in different regions of the bipolar plate. Specifically, the flow paths are adjusted to provide increased coolant flow to regions with higher heat generation (such as near gas discharge ports), while maintaining standard configuration in other areas. This regional differentiation allows the cooling system to address local thermal characteristics, achieving more uniform temperature distribution across the fuel cell stack.

The patent employs dynamics by implementing a flow diversion mechanism that dynamically redirects coolant flow based on thermal requirements. A diversion member is positioned to redirect a portion of the coolant flow from the main flow path into a bypass flow path that leads to the designated region. This dynamic flow distribution allows the system to enhance cooling capacity in specific areas without adding additional coolant inlets, thereby maintaining device simplicity while achieving improved thermal management.

The patent applies segmentation by dividing the coolant flow system into distinct flow paths: a main flow path and a bypass flow path. The diversion member creates a clear separation between these paths, allowing independent control and optimization of flow distribution. This segmented approach simplifies the manufacturing process compared to creating complex integrated flow patterns, as each segment can be manufactured and assembled separately with standard precision requirements, while still achieving the desired non-uniform flow distribution for improved temperature management.
