A fuel cell is an electrochemical cell that converts chemical energy into electricity. It uses the chemical energy of hydrogen or other fuels to produce electricity, water, and heat. Fuel cells can be used in a wide range of applications, including transportation, material handling, and stationary, portable, and emergency backup power. Fuel cells are made up of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. They produce electricity and heat as long as fuel is supplied. Fuel cells are pollution-free and can have more...

Fuel cells can be used in a wide range of applications, including transportation, material handling, and stationary, portable, and emergency backup power. Fuel cells are made up of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. They produce electricity and heat as long as fuel is supplied. Fuel cells are pollution-free and can have more than two times the efficiency of traditional combustion technologies. They emit less carbon dioxide per kWh of power generation than other fuel-based power systems. If the fuel is biogas, the power is carbon neutral. Some types of fuel cells include: Solid oxide fuel cells: These cells have very high operating temperatures (600–1000°C) and are limited to stationary applications. Phosphoric acid fuel cells (PAFC): These cells use phosphoric acid as the electrolyte and have an operating temperature of 150–200°C. Alkaline (AFC): These cells use aqueous potassium hydroxide soaked in a porous matrix, or alkaline polymer membrane. Show less
