Abstract: PRESSURIZED FUEL CELL POWER PLANT WITH      STEAM POWERED COMPRESSOR     ABSTRACT OF THE DISCLOSURE    A fuel cell power plant for producing electricity uses pressurized air and fuel in the cells.  A compressor is driven by a turbine operably connected thereto and provides compressed air to the cells.  The turbine is driven by a working fluid in a hot, pressurized, vapor state.  Energy to convert the working fluid into this state is waste energy produced by the power plant, such as stack waste heat.  In one embodiment the power plant includes a steam reforming reactor and a reactor burner.  Effluent gases from the anode side of the cell are used in the reactor burner.          The working fluid is water and the turbine is driven by steam which is condensed to the liquid state after passing through the turbine.  The liquid water is reconverted to steam by passing it into heat exchange relationship with the stack and it is then delivered again into the turbine.  Part of the steam may be used in the steam reforming reactor.  Preferably the effluent gases from the reactor burner and the effluent gases from the cathode side of the cells is delivered into an air turbine for generating electrical power in addition to the electrical power produced in the fuel cells.

Abstract: ABSTRACT OF THE DISCLOSURE.     A current-limiting device for an alternating current system has for each phase a pair of saturable reactors each with an iron core, an alternating current winding and a supcrconducting direct current bias winding which is common to the reactor cores and biases them both to saturation.   The two alternating current windings in each phase are connected in series opposition such that under fault conditions they are driven out of saturation on alternate half-cycles and thus limit the overload current.   The superconducting winding hafi a surrounding magnetic flux screen which also forms a loop for shlmting alternating current under fault conditions and which may be used as a direct current control circuit for varying the bias level.   The screen serves as the outer vessel of an evacuated enclosure for the superconducting winding and a support system for the inner vessel is also described.
