Electrolysis system with cathode recirculationEffect of heat supply on efficiency 外部供热对系统效率的影响 goal for LT(incl. gas compressionto 70 bar)h2 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 (300~400°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:- 9~30 Ah per 80cm²- 84~95% round trip efficiency- 300 cycles without stack degradation C.
