FUEL CELL EXHAUST FLUID DROPLET REDUCTION

Patentradars sammanfattning

Volvo Truck Corporation discloses an exhaust fluid droplet reducer (110) positioned downstream of a fuel cell system in a fuel cell electric vehicle. The device comprises concentric first and second fluid passageways that can be axially or rotationally displaced relative to each other to open or close a circumferential gap, selecting between a first (winter) mode where the inner surface seals the passageways and a second (non-winter) mode where an opening diverts large droplets to a discharge reservoir or external environment. Optional turbine wings and a mechanically confined actuator track with locking positions enable both manual and motorized mode switching, directly reducing large droplet formation at the source rather than relying solely on chimney height.
