What's mean Types of fuel cells-SOFC system? What's mean Types of batttery fuel cells-SOFC system?The SOFC is best suited for
stationary applications. The system requires high operating temperatures
(about 1000°C). Newer systems are being developed which can run at about 700
°C. A significant advantage of the SOFC is its leniency on fuel. Due to the high
operating temperature, hydrogen is produced through a catalytic reforming
process. This eliminates the need for an external reformer to generate
hydrogen. Carbon monoxide, a contaminant in the PEMFC system, is a fuel for
the SOFC. In addition, the SOFC system offers a fuel efficiency of 60
percent, one of the highest among fuel cells. The 60 percent efficiency is
achieved with co-generation, meaning that the heat is utilized. Higher stack temperatures add to the manufacturing cost because they require
specialized and exotic materials. Heat also presents a challenge for
longevity and reliability because of increased material oxidation and stress.
High temperatures, however, can be utilized for co-generation by running
steam generators. This improves the overall efficiency of this fuel
