The delivery system provides a hydrogen-production fluid to the hydrogen-producing region and provides a heating fuel to the heating assembly. The delivery system includes a pressure vessel having an interior cavity containing the heating fuel and the hydrogen-production fluid, which are disposed in the pressure vessel in a pressurizing-pressurized relationship, in which the heating fuel is discharged from the pressure vessel under it own pressure and the hydrogen-production fluid is discharged under pressure applied by the heating fuel. The feedstock delivery system may separately discharge the hydrogen­production fluid and the heating fuel and may include a pressure transmitter disposed between the hydrogen-production fluid and the heating fuel. The heating fuel may be a condensable fluid and the hydrogen-production fluid may be a liquid at the operating conditions of the feedstock delivery system.

Abstract: Fuel cell systems and methods for controlling the operation of components of the fuel cell system, which may include a fuel source and a fuel cell stack. In some examples, a fuel source is adapted to provide supply fuel to a fuel cell stack at a supply pressure. The fuel cell stack produces electric current at a production amperage. In some examples, a control system is adapted to control operation of the fuel cell stack based on a pressure detected at the fuel cell stack. In some examples, a target production amperage is determined based on the detected pressure, such that when electric current is produced at the target production amperage for the detected pressure, the fuel cell stack consumes a predetermined proportion of the supply fuel.
