Abstract

Real-time monitoring and control of solid oxide fuel cell (SOFC) systems is are important to identify and understand cell performance. Some parameters that affect the performance of SOFC cells include fuel flow rate, furnace temperature, and the cell material itself. These parameters have a correlation with each other in making SOFC cells to be applied as a substitute for alternative energy. This results in a reliable SOFC cell, optimal output voltage and lower operating temperature. Because so far the material of SOFC cells is ceramics that have a working temperature range between 500–1000 °C. Monitoring is limited by the SOFC operating environment around the furnace. SOFC operations are limited to hydrogen and oxygen fuel flow channels. The maximum furnace operating temperature is 1000 degrees, and the minimum output voltage for one cell. Therefore, it is necessary to place sensor sensing points as needed. This study aims to design a monitoring and regulation system for hydrogen/oxygen flow in the SOFC operating environment based on the Arduino Mega 2560 microcontroller and computer interface. Valve control uses open-loop and on-off control methods. Open-loop control is used to set the valve rotation angle value. While the on-off control to close the valve automatically when there is an excess concentration of hydrogen in a laboratory room. The system is designed for the needs of laboratory-scale experiments on simple furnaces. This device also functions as a simple mini prototype module. So that it can be used as material to learn and understand the SOFC system widely. The prototype test results show that the flow of hydrogen can be adjusted from 0.07–4.74 L/min and oxygen can be adjusted between 0.24–4.8 L/min. Temperature sensors have an average error of 2.6 % and voltage sensors have an accuracy of 0.1 V
