Abstract

The invention discloses a device and method of a DIR-SOFC with support of a heat pipe. An anode premixing cavity and an anode combustion cavity are arranged in the top and bottom ends of the fuel cellrespectively, the high-temperature heat pipe is arranged in the inner wall of the fuel cell, fuel enters the anode combustion cavity from the anode premixing cavity, the heating end of the high-temperature heat pipe is heated by combustion, a heat-conducting medium in the high-temperature heat pipe is evaporated, and is condensed and releases heat in the process from the heating end to a condensation end, and the fuel cell is started rapidly; rapid heat conduction is realized between an internal reforming reaction area and an electrochemical reaction area in the fuel cell via the high-temperature heat pipe, and the problems of non-uniform temperature distribution and thermal stress caused by different heat effects of the two areas in the DIR-SOFC can be solved effectively; more heat energy released by electrochemical reaction can be converted to chemical energy of a reforming product; and thus, the performance and life of the fuel cell are both improved.

Description

technical field [0001] The invention relates to solid oxide fuel cell technology, in particular to a heat pipe supporting direct internal reforming solid oxide fuel cell device and method. Background technique [0002] Solid oxide fuel cell (SOFC) is a power generation device that can directly convert the chemical energy of fuel into electrical energy at high temperature. It has broad application prospects in the fields of stationary power stations, power supplies, and portable power supplies. [0003] When hydrocarbon fuels are used as fuel in SOFCs, a reforming reaction process is usually required to convert them into H 2 and CO to improve the performance and life of SOFC. The high temperature operation of SOFC makes it possible to pass hydrocarbon fuel and oxidant (usually water vapor or carbon dioxide) into the anode of SOFC, and realize the reforming reaction process of hydrocarbon fuel inside the anode, forming a direct internal reforming solid oxide fuel battery (DI...
