| PureCell™ Solution An Inside Look |
Inside the PureCell™ system
1. Fuel Processor (Reformer) The fuel processor reforms the fuel (natural gas or anaerobic digester gas) to a hydrogen rich gas to feed the fuel cell stack.
2. Fuel Cell Stack Hydrogen rich gas and oxygen from the air are combined in an electro-chemical process that produces direct current (DC) power, pure water and heat. The byproduct water is used in the operation of the powerplant. The waste heat is available through an integral hot water heat exchanger for use in meeting other facility thermal energy requirements.
3. Power Conditioner The DC power provided by the fuel cell stack is conditioned to provide high quality alternating current (AC) output power.
4. Electronics and Controls Each PureCell™ system can be remotely controlled and monitored.
