Abstract

The invention relates to an SOFC tail gas utilization research experiment system which comprises a gas supply device, a heating device, a combustion device and a measurement device which are connectedin sequence. The gas supply device is used for generating compressed air and SOFC tail gas with different component contents; the heating device is used for heating the compressed air and the SOFC tail gas; the combustion device is used for mixing the SOFC tail gas and compressed air and carrying out combustion reaction; the measurement device is used for measuring technological parameters in theSOFC tail gas combustion reaction process. Compared with the prior art, different working conditions of an SOFC stack can be simulated, and the system has the advantages that parameters are easy to adjust, control is accurate, and SOFC tail gas components can be efficiently configured.

Description

technical field [0001] The invention relates to the technical field of SOFC tail gas utilization, in particular to a research experiment system for SOFC tail gas utilization. Background technique [0002] Fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. It has been hailed as the fourth generation of power generation technology after water power, thermal power and nuclear power. Solid oxide fuel cell (SOFC) is the third-generation fuel cell system with the highest energy conversion efficiency after phosphoric acid fuel cell (PAFC) and molten carbonic acid fuel cell (MCFC). It has strong adaptability to fuel and high waste heat temperature. , It can be directly used for cogeneration of heat and power, and the comprehensive utilization rate of fuel is high. SOFC has more development potential in the future power generation market. The development, research and commercialization of SOFC is an important means to solve the world's e...
