focus resources on programs that will contribute most to solving the problems critical to the success of the long-term program goals.

Value of Learning Demonstrations

Conclusion. The learning demonstrations program is very important to validate current component and systems concepts and to uncover previously unknown issues. Such demonstrations will establish many system and engineering parameters for a complete operating hydrogen supply and a fuel cell transportation system. These cooperative programs are well designed. Information will be collected from both vehicle and infrastructure components, pooled, and shared. It will guide the technical teams as well as the systems and modeling efforts and help to establish appropriate program priorities.
