Fuel Cells Explained

A fuel cell is an electrochemical device in which fuel is oxidized without combustion to generate electrical energy (direct energy conversion)

Competitive Advantage: SOFC vs Solar / Wind

• Solar, while clean, is only available 18% of the time on average. • Dirty, grid electricity (“brown power”) is required the other 82% of the time.• SOFC is available 24 hours a day; making it a cleaner, cheaper alternative
