Deja, L. Blum, V.N. Nguyen, Q. Fang, D. Stolten, Influence of operating parameters on overall system efficiencies using solid oxide electrolysis technology, International Journal of Hydrogen Energy, 40 2015 7103-7113. Electrolysis system with cathode recirculationEffect of heat supply on efficiency 外部供热对系统效率的影响 goal for LTincl. gas compressionto 70 barh2 h3 h4 SUMMARY- A decarbonized energy system in the EU needs H2 energy- Electrolysis with renewable energy has long-term potential for H2 production and energy storage- Germany is leading the fuel cell and H2 activity in the EU- The EU’s current focus on fuel cell and H2 technology is to increase the TRL- SOC technology can be demonstrated in the laboratory from the cell to system level- Stable performance of SOCs demonstrated at the stack level up to kW SOLID OXIDE CELL SOC FOR STATIONARY APPLICATIONS 22 As a power generator SOFC mode- Highest conversion efficiency- No precious metals necessary- High waste heat temperature level 300400°C- High tolerance against pollutions from fuel gas- H2, CO, CH4 and other hydrocarbons as fuel are possibleAs a gas generator SOEC mode- Lower electrical energy demand  higher electrical efficiency with external heat supply- CO 2 electrolysis or co-electrolysis possibleReversible mode rSOC- 2-in-1 system- Increased application flexibility 高温为固体氧化物电池SOC提供了优势，但同时也决定了其固定式的主要应用场景 23 RECHARGEABLE OXIDE BATTERY ROB 可充电式氧化物电池 Demonstrated- 930 Ah per 80cm²- 8495 round trip efficiency- 300 cycles without stack degradation C.
