Fuel cells are an entirely different approach to the production of electricity than traditional prime mover technologies. Fuel cells are silent, produce no pollutants, and have minimal moving parts. Fuel cells produce power electrochemically from hydrogen delivered to the negative pole (anode) of the cell and oxygen delivered to the positive pole (cathode). The hydrogen can come from a variety of sources, but the most economic method is by reforming natural gas or liquid fuels. There are several different liquid and solid media that support these electrochemical reactions – phosphoric acid (PAFC), molten carbonate (MCFC), solid oxide (SOFC), and proton exchange membrane (PEM) are the most common systems.
