6114Endurance and Reliability

Fuel cells could be great sources of premium power if they could be demonstrated to have superior reliability and power quality and could be shown to provide power for long continuous periods of time. The power quality of fuel cells alone could provide the most important marketing factor in some applications and, coupled with longevity and reliability, would greatly advance fuel cell technology.

Although fuel cells have been shown to be able to provide electricity at high efficiencies with exceptional environmental sensitivity, the long-term performance and reliability of certain fuel cell systems have not been significantly demonstrated to the market. Research, development, and demonstration of fuel cell systems that will enhance the endurance and reliability of fuel cells are currently underway. The specific RD&D issues in this category include (1) endurance and longevity, (2) thermal cycling capability, (3) durability in installed environment (seismic, transportation effects, etc.), and (4) grid-connection performance.

Solar Stirling Engine Basics Explained

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
