Centrifugal Water Pump Driven With a DC Motor Powered by an Emulator of MK5-E Proton Exchange Membrane Fuel Cell Stacks
Direct Current (DC) motors can be directly powered by Proton Exchange Membrane Fuel Cell (PEMFC) Stacks, to obtain plants with little maintenance and good reliability. To obtain a suitable efficiency working plant, it’s necessary to correctly match the load in order to operate in proximity to the best power line of the FC stacks generator. Otherwise by a proper field current regulation of a separately excited DC motor directly powered by a FC stacks generator, it is possible to extract from the generator itself the correct power for every temperature level. The present interest for this problem has advised the Authors to perform an experimental investigation, whose results are reported in t…
Analysis of a Gas Turbine Almost Real Open Cycle Linked to the SOFC Module Behaviour
Solid oxide fuel cells (SOFCs) are particular promising electrochemical generators for their high operating temperature that makes them suitable for integration with gas turbine cycles and cogeneration. The kind of fuel cell taken into account is the tubular SOFC technology, mainly developed by Siemens-Westinghouse. The SOFC module is fed with natural gas with internal reforming and internal air preheating. Elevated pressures are adopted in order to increase both fuel cell efficiency and power density. The inlet air temperature is set to 630 °C, and the inlet fuel temperature to 200 °C. The heat generated by irreversibility at the electrodes structure is given to the fuel and air flow, and …
