Real-Time Power Management Of A Fuel Cell/Ultracapacitor Hybrid, Wesley Greenwell May 2008

Real-Time Power Management Of A Fuel Cell/Ultracapacitor Hybrid, Wesley Greenwell

All Theses

This thesis presents the system architecture design, system integration methodology, and real-time control of a fuel cell/ultracapacitor hybrid power system. The main objective is for the hybrid system to respond to real-world fluctuations in power without negatively impacting fuel cell life.
A Proton Exchange Membrane (PEM) Fuel Cell is an electrochemical device which converts the chemical energy of pure hydrogen into electricity through a chemical reaction with oxygen. The high conversion efficiency, zero harmful emissions, high power-to-weight ratio, scalability, and low temperature operation make PEM fuel cells very attractive for stationary and portable power applications. However, fuel cells are ...
