Full Description

When used in distributed generation (DG) applications, fuel cells have the potential to save energy and reduce emissions. Their inherent fuel-flexibility also could help address energy shortage issues through energy diversity. In addition, fuel cells have the potential to be quieter, more reliable, and have lower maintenance costs than most technologies used for DG.

This is the second in a series of articles on fuel cells for DG applications. This article addresses solid-oxide fuel cells (SOFC). An article in last month’s issue addressed polymer electrolyte membrane (PEM) fuel cells.
