C and 100 MPa), resulting from that high efficiency and lack of noble metals catalysts, low operating voltage, much higher current density in comparison with PEM and alkaline, possibility of combined operation with heat sources like power Rankine or Joule cycles. The main drawbacks are: high costs of ceramic cells resulting from materials used and production, fast cell degradation and fatal durability to load fluctuations due to high operation temperature.
