Reversible Fuel Cell RFC Controls

On the other hand, when solar electricity is insufficient and needs to be supplemented, the RFC is switched into the fuel cell mode of operation where the oxidation of one mol of hydrogen will generate 237.1 kj/mol of electrical energy plus 48.7 kj/mol of thermal energy. This waste heat can also be used for heating buildings or for preheating boiler feedwater. 

In addition to the electric controls that control the grid connection and the conversion between direct and alternating current circuits, a massive

In addition to electric, pressure, and temperature controls, the loads (the rates of hydrogen or electricity generation) also need to be controlled. These
