63 Comparison of Fuel Cell Types

Table 6.1 presents a summary comparison of the four primary fuel cell types under serious consideration for distributed power generation (e.g., MCFC, PAFC, PEMFC, and SOFC). Notice that the higher-temperature fuel cells do not require an external reformer. The PAFC and PEMFC units tend to use precious metal catalysts, while catalysts of the MCFC and SOFC units are typically nickel based. These differences lead to many variations in design and function which will be described in more detail in the next section.

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.
