How to Set Up the Voltage in SOEC Electrolysis?

  This like in the ANSYS Guide is quite confusing:
  
  Considering an OCV = 0.84V and V_cell = 1.3 V:
  Does that mean that in the Tab of the Anode we set up -1.3V and V_cathode = 0? That would be a V_cell = V_cathode - V_anode = +1.3V, with an OCV of 0.84V (the voltage has to be superior for the reactions to happen)?
  In some other parts of the guide it is recommended to keep Tab Anode = 0V. Should I then set up V_cathode = 1.3 and V_anode = 0?
  
  Thanks beforehand!

  Hello Raul,
  V_cathode = 1.3V and V_anode = 0V in electrolyzer. That is the convention followed in Ansys Fluent.
  Thank you.
