What type of fuel cell has ClearEdge Power developed?

The ClearEdge5 uses a Proton Exchange Membrane, also known as a Polymer Electrolyte Membrane (PEM). The PEM operates around 150°C; this is a relatively low-temperature fuel cell compared to a Solid Oxide Fuel Cell (SOFC) which runs between 500°C – 1,000°C. At a lower operating temperature, the system is less prone to system failure or less sensitive to starting and stopping. This lower temperature allows for the efficient capture of heat for use in the building and high overall efficiency.
