High-Temperature Blower for Molten Carbonate Fuel Cell Supported By Magnetic Bearings
The high-efficiency Molten Carbonate Fuel Cell is a next-generation, clean power source. One critical requirement of this power source is that it needs a high-temperature blower capable of recycling 700X^ cathode gas. The blower should be oil-free and have an extended life cycle. We have developed a high-temperature blower, supported by magnetic bearings, which fulfills this requirement. The rotor mass of the blower is 80 kg and the designated speed of the rotor is 12000 min' 1 . We carried out a 1500-hour continuous rotation test of a 500 kW MCFC test apparatus. The system was operational even when the temperature of the magnetic bearing reached to about 400*0.
