For the air cooled fuel cell reactor, by adjusting the fan voltage, changing the speed of the fan and controlling the temperature of the reactor, the heat management of the reactor is realized by adjusting the voltage of the circulating water pump, changing the flow rate of the cooling water and controlling the temperature of the reactor. Set the opening and closing cycle and duty ratio of the solenoid valve, regulate the emission of the tail gas, control the humidity inside the stack, and realize the water management of the electric reactor.
Applying the linear load (rheostat) and the light bulb load provided, the current, voltage and power characteristics of the stack are preliminarily understood by observing and displaying the instrument. Using the electronic load provided, the experiments of constant current, constant voltage, constant power and constant resistance are carried out. The V I and P I curves under different loads are plotted, and the output characteristics of the reactor are studied. The V I curve of fuel cell stack was drawn, and the V I curve of air-cooled fuel cell stack was drawn.
The control unit of the fuel cell power generation system is the core of the whole experimental device. By controlling the temperature of the fuel cell reactor, the pressure of hydrogen, the air volume and the exhaust emission, the heat management and water management of the fuel cell power generation system are realized. For different loads, the stack characteristics under constant current, constant voltage, constant power and constant resistance can be studied and the corresponding characteristic curves can be drawn.
By adjusting and optimizing the control variables, the optimal operation conditions are determined and the optimal output performance of the system is obtained. For different types of electric reactors, the performance of the stack is evaluated by comparing the characteristic curves of the stack.
