Abstract
An apparatus for delivering a primary fuel stream to a fuel cell stack is provided. The apparatus includes an ejector that is configured to receive the primary fuel stream from a fuel supply. The apparatus is further configured to receive the recirculated fuel stream from the fuel cell stack to provide a combined fluid stream for delivery to the fuel cell stack. The ejector includes an elastic conduit for varying a flow of the combined fluid stream based on a power level of the fuel cell stack.
Claims20
An apparatus for delivering a primary fuel stream to a fuel cell stack that discharges a recirculated fuel stream, the apparatus comprising:
- an ejector configured to receive the primary fuel stream from a fuel supply and to receive the recirculated fuel stream from the fuel cell stack to provide a combined fluid stream for delivery to the fuel cell stack, the ejector including an elastic conduit for varying a flow of the combined fluid stream based on a power level of the fuel cell stack.
A vehicle apparatus comprising:
- an ejector configured to receive a primary fuel stream from a fuel supply and to receive a recirculated fuel stream from a fuel cell stack to provide a combined fluid stream for delivery to the fuel cell stack to generate power, the ejector including an elastic conduit for varying a flow of the combined fluid stream based on a power level of the fuel cell stack.
A vehicle apparatus comprising:
- an ejector configured to receive a primary fuel stream from a fuel supply and to receive a recirculated fuel stream from a fuel cell stack to provide a combined fluid stream for delivery to the fuel cell stack to generate power, the ejector including an elastic conduit for having a geometry thereof adjusted based on a power level of the fuel cell stack.
