描述
Engineering Breakthrough --Thermodynamics in SOEC-CH₄
ceramic cells
描述
· Excessive heat released from methane oxidation in the anodes is quickly transferred through thin dense electrolytes to promote endothermic steam splitting in the cathodes
· Theoretical electricity consumption:
  √. 0.78 kWh/Nm³ H₂
  √. 8.6 kWh/kg H₂
