Yesterday, we witness the unveiling of an eco-friendly fuel cell. It's a product that got a lot of people excited as it generates electricity with only by products like water, heat and some carbon dioxide. To be exact, they operate using Solid Oxide Fuel Cell.

A solid oxide fuel cell (SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material and, as the name implies, the SOFC has a solid oxide, or ceramic, electrolyte. Advantages of this class of fuel cells include high efficiencies, long term stability, fuel flexibility, low emissions, and cost. The largest disadvantage is the high operating temperature which results in longer start up times and mechanical/chemical compatibility issues.
