Facts

• Alkaline fuel cells were first applied on space missions.

• They have power efficiencies of up to 70%.

• They use alkaline potassium hydroxide as the electrolyte.

• Until recently they were to expensive for commercial applications, but several companies are examining ways to reduce costs and improve operating flexibility.
