Abstract
System and methods for removing water and/or other liquids from a fuel cell system at a variety of vehicle tilt orientations are disclosed. In certain embodiments, a method for regulating a sump system in a vehicle may include receiving orientation information from one or more orientation sensors associated with the vehicle and/or the sump system. Based on the orientation information, an adjusted fill level of the sump system may be determined (e.g., using a look-up table or the like). A drain valve of the sump system may be selectively actuated to regulate a level of liquid in the sump system at or below the adjusted level.
