Fuel cell coolant bubble control
To mitigate bubble blockage in water passageways, in or near reactant gas flow field plates of fuel cells, passageways are configured with (a) intersecting polygons, obtuse angles including triangles, trapezoids, or (b) hydrophobic surfaces, or (c) differing adjacent channels, or (d) water permeable...

| Zusammenfassung: | To mitigate bubble blockage in water passageways, in or near reactant gas flow field plates of fuel cells, passageways are configured with (a) intersecting polygons, obtuse angles including triangles, trapezoids, or (b) hydrophobic surfaces, or (c) differing adjacent channels, or (d) water permeable layers adjacent to water channels or hydrophobic/hydrophilic layers. |
