URFC Unitized Regenerative Fuel Cell
A Unitized Regenerative Fuel Cell (URFC) is a regenerative fuel cell (RFC) with both processes done in the same fuel stack. It is a Proton-Exchange Membrane Fuel Cell (PEM) style using usually hydrogen and oxygen. Reasons for development of this compact unitized RFC is less weight and mass.
A URFC combines an electrolyzer that separates the water molecules to make and store hydrogen and oxygen and reverse the process to combine the two elements and make electricity and H2O (water).
