POWER SYSTEM Russian patent published in 2003 - IPC

FIELD: power systems built around fuel cells. SUBSTANCE: power system has at least one unit of electrochemical fuel cells whose dc output current is converted to ac supply; chemical agents storage, delivery, discharge, and distribution system; channels for discharging products of chemical reaction; turbine unit; ac current regulator, and ac current frequency stabilizer; system provides for adding and matching outputs of ac current generated by fuel cell unit and turbine unit. The latter is made in the form of thermomagnetic device incorporating centrifugal turbine whose running blades are placed in magnetic field of system. Heat flux produced in the course of operation of fuel cells is converted into mechanical energy for centrifugal turbine rotation by feeding heat flux to mentioned blades in location of external magnetic system as they leave effective range of external magnetic system attraction to ensure their heating to temperature of their magnetically soft material transition to paramagnetic state. Air supplied to fuel cell unit for oxygen extraction is also used to cool down mentioned blades to temperature below that of their transition from magnetically soft to paramagnetic state. Some portion of dc energy produced by fuel cells is used to build up magnetic field around external magnetic system of centrifugal turbine. EFFECT: enhanced efficiency of utilizing fuel as well as specific and total output power.. 1 cl, 1 dwg
