WATT is a Fuel Cell.

A fuel cell is a simple electrochemical device that directly converts the chemical energy stored within fuels into usable energy. WATT’s Solid Oxide Fuel Cells (SOFCs) are ceramic-based and tubular, enabling them to thermal cycle and load follow.

SOFCs can run on natural gas, propane, renewable natural gas, and hydrogen – including blends – making fuel cells a versatile technology that can flex between available and desired fuel options.

In a fuel cell, fuel and oxygen are combined to generate electricity, heat, and water(steam):

  1. Fuel is delivered to the anode while oxygen goes to the opposing cathode.
  2. At the cathode, oxygen molecules are electrochemically reduced into oxide ions.
  3. These oxide ions pass through the electrolyte.
  4. At the anode, oxygen and hydrogen ions combine to produce water molecules.1
  5. Electrons are transported from the anode to the cathode through an external circuit, generating an electrical current.

1Operating on natural gas or propane, the process also yields heat and a small amount of carbon dioxide.

What are the most powerful attributes of electricity generated by WATT’s SOFCs?​

  • High efficiency (far-exceeding traditional combustion engines, solar, and wind)

  • Extremely low CO2  emissions

  • Virtually zero criteria pollutants (NOx, SOx, ozone, fine particulates)

One Power Source. Unlimited Possibilities.
