An Alkaline Fuel Cell (or Hydrogen-Oxygen Fuel Cell) is a type of fuel cell that is operated on compressed hydrogen and oxygen, and operating temperature is 150 to 200°C. The Alkaline Fuel Cell uses an alkaline electrolyte such as the potassium hydroxide (KOH) or an alkaline membrane conducted hydroxide ions rather than protons. Originally used by the National Aeronautics and Space Administration (NASA) as a primary source of electrical energy in the Apollo space program. The Alkaline Fuel Cell is now finding new applications, such as in portable power.
