Air motor drive for fuel cell power plant air circulator

摘要

Disclosed is an air motor/fan circulator system for circulating air around a fuel cell power plant circuit. The system requires no steam, gas, or electrical penetrations into the fuel cell power plant circuit and further meets the requirements of being able to circulate in excess of one million pounds-mass per hour around the circuit through a pressure difference of about one pound per square inch. The system is suitable for use under fuel cell power plant conditions: a system pressure of several atmospheres and a system temperature of several hundred degrees.
