Sommario/riassunto |
|
Fuel cell system is an advanced power system for the future that is sustainable, clean and environmental friendly. The CFD models in this book would allow the creation of powerful computational fuel cell engineering tools that lead to dramatic reductions in lead times and development costs, and spur innovative design. |
