Micro Steam Turbines

Refrigeration cycles can also be implemented in microsystems. The vapor compression cycle, which is the inverse of the Rankine cycle micro steam turbine), consists of compressing a gas and...

The carbonate ions are transported towards the anode electrode through the electrolyte, which is an eutectic carbonate melt The cathodic exhaust gas leaves the fuel cell and, due to its high temperature of about 500 °C, it can be used for subsequent steam generation, for additional production of electric energy via a micro turbine or for other purposes. 

Boiling water acts as coolant and moderator, while separated steam is used to drive the turbine. Maintenance of the water chemistry is performed by the systems that are conventional for reactors of BWR type. The coolant circuit equipment is made of stainless steel, or has a welding deposition made of stainless steel. The fuel assemblies are also made of stainless steel. The outer coatings of micro fuel elements are made of silicon carbide (SiC). 

Fuel cell power systems contain an assembly of electrochemical cells, which oxidize a fuel to generate direct current electricity. Balance-of-plant subsystems may include controls, thermal management, a fuel processor, and a power conditioner. Some fuel cell power systems may contain additional power generating equipment such as steam generators, gas turbine generators, or micro-turbine generators. The net power output and all the fuel input to the system shall be taken into account in the performance test calculations.
