A high-temperature fuel cell teaching instrument

Abstract

The invention discloses a high-temperature fuel cell teaching instrument, which comprises a heating start module, an air inlet module, a battery working module, an exhaust gas analysis module, an exhaust gas treatment and waste heat recovery module. The heating start module uses the high-temperature tail gas generated by the natural gas combustion to heat the fuel cell stack to a specified temperature; the heating start module uses the high-temperature tail gas generated by the natural gas combustion to heat the fuel cell stack to a specified temperature. The intake module regulates the intakeair quantity of the cathode and anode of the fuel cell stack; The battery work module monitors the output power and other information of the fuel cell stack in real time. The tail gas analysis modulecarries out real-time analysis on the composition of the cathode and anode tail gases; The tail gas treatment and waste heat recovery module converts the chemical energy in the cathode and anode tailgases into mechanical energy and thermal energy through a combustion and turbine. The invention solves the safety problems in the transportation and storage of the fuel required by the high-temperature fuel cell teaching instrument. The fuel cell stack can be monitored in real time. It is convenient for students to analyze the working principle of fuel cell by parameterization.

Description

technical field [0001] The invention belongs to the technical field of teaching instruments, and in particular relates to a high-temperature fuel cell teaching instrument. Background technique [0002] With the continuous aggravation of environmental pollution and energy crisis, fuel cells have received more and more attention. Compared with traditional energy conversion methods, the energy conversion process of fuel cells is clean and efficient. The popularization of fuel cells requires the preparation of corresponding teaching instruments to help students understand the working principle of fuel cells. As one of the current mainstream fuel cell types, the solid oxide fuel cell usually operates at a temperature of 600°C-1000°C. Due to the high working temperature, there are many potential safety hazards in the preparation of corresponding teaching instruments. In addition, how to more clearly show the complex working principle of the fuel cell and how to obtain fuel conv...
