Abstract
Systems and methods are provided for regulating fuel cell backpressure or humidity in conjunction with a flow control assembly that recovers energy resulting from the regulation. An exemplary vehicle system includes a fuel cell stack, a flow control valve to regulate a fluid flow exiting the fuel cell stack, and a flow control assembly parallel to the flow control valve to generate electrical energy in response to a bypass portion of the fluid flow that bypasses the flow control valve based on an orientation of the flow control valve with respect to the fluid flow.
