    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.

    Abstract: A supercritical carbon dioxide state monitoring and control system based on infrared spectrum characteristic analysis. The system includes: a test section for carbon dioxide to pass through; an infrared light source emitting a detection beam to the carbon dioxide passing through the test section; an infrared spectrometer receiving and analyzing the detection beam passing through the carbon dioxide; and a pressure control module controlling pressure of the carbon dioxide at a set value. In addition, the system also includes a temperature control module capable of monitoring and adjusting temperature of the supercritical carbon dioxide. The supercritical carbon dioxide state monitoring and control system may monitor and control a state of the carbon dioxide at an inlet of an apparatus under an actual operation condition in a Brayton cycle system, which improves working performance of the apparatus in the Brayton cycle system, thereby improving overall efficiency of the Brayton cycle system.

    Abstract: Receiving and storage of energy, and particularly a particle solar receiver for solar thermal power generation. The particle solar receiver includes: a feeding bin temporarily storing endothermic particles to be heated, and a multi-stage plate heat absorbing channel allowing the particles to flow along a predetermined path by gravity, where the multi-stage plate heat absorbing channel includes a plurality of plate-type structures which forms a changing flow direction of the particles flowing between adjacent plate-type structures. The particle solar receiver can achieve the endothermic particle heating function with a simple structure, i.e., the function of converting the solar power into thermal energy at a high-temperature level.
