Abstract: A system and method for complementarily coupling and orderly converting multi-energy. The system includes: a reversible solid oxide cell, a gasification reaction chamber, synthesis reactor, and photo-thermal coupled catalytic reactor. Gasification of biomass/coal provides synthesis gas of a first source; feedstock gas is electrolyzed to produce synthesis gas of a second source; the synthesis gas of a first source and the synthesis gas of a second source react in the synthesis reactor to produce hydrocarbon fuel; during power generation, the synthesis gas enters a fuel electrode to react, and gas flowing out of the fuel electrode passes through the photo-thermal coupling catalytic reactor to react to produce hydrocarbon fuel; a heat source and light source required for gasification, electrolysis, power generation and photo-thermal coupled catalysis are provided by solar energy, and electrical energy for electrolysis is provided by power of unstable renewable energy from abandoned wind and light.

Abstract: The present invention relates to a carbon-assisted solid oxide electrolysis cell comprising: a cathode, an electrolyte, an anode, and an anode chamber set in the order. The cathode is supplied with water as an oxidant and the reduction reaction occurs. The anode chamber includes carbon fuel and CO2 absorber, supplied with the water as in situ gasification agent, wherein the water assists the gasification of the carbon fuel to generate CO and H2. The O2− ions generated by cathode are transported to the anode through the electrolyte, and react with CO and H2 generated in the anode chamber as oxidant. The CO produced by the carbon gasification reaction partly reacts with water to generate CO2 and H2, while the CO2 absorber promotes the production of H2 by absorbing the CO2 produced by the water gas shift reaction. The present invention can control the internal gas composition of the CA-SOEC anode effectively, improving the performance of the carbon-assisted electrolysis cell and reducing energy consumption. Furthermore, the present invention achieves the simultaneous generation of fuel gas by the cathode and the anode, significantly improving the efficiency of the electrolysis.
