Abstract: A fuel cell system and method of controlling the fuel cell system are provided. The fuel cell system includes a fuel cell stack that is configured to receive fuel, and generate electric energy and a fuel supply valve that is configured to adjust pressure of fuel that is supplied to the fuel cell stack. A controller is configured to operate the fuel supply valve to supply fuel of predetermined target pressure to the fuel cell stack, using a difference between the predetermined target pressure and actual pressure of the fuel being supplied. When the actual pressure reaches a steady state from a transient state, the controller applies a smaller gain than in the transient state to determine a first controlled variable based on the difference between the target pressure and the actual pressure of the fuel being supplied.

Abstract: A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.
