Abstract

Proton Exchange Membrane Fuel Cell atau biasa disingkat PEMFC merupakan salah satu sumber energi terbarukan yang saat ini layak untuk dipertimbangkan. Selain penggunaan bahan bakar yang ramah lingkungan, PEMFC juga dapat beroperasi di temperatur yang relatif rendah yaitu sekitar 40℃-60℃. Untuk memperoleh performansi PEMFC yang optimal diperlukan kontrol sistem, salah satunya yaitu kontrol temperatur stack agar tetap pada rentang 40℃-60℃. Dalam penelitian ini, sistem kontrol dilakukan dengan menggunakan kontroler PI, variabel kontrol adalah temperatur stack sedangkan variabel yang dimanipulasi adalah laju aliran (flow rate) dari coolant. Pemodelan dilakukan dengan menggunakan software MATLAB Simulink. Hasil validasi model menunjukkan nilai Root Mean Square Error (RMSE) sebesar 0,006. Selanjutnya telah dilakukan pengujian terhadap model. Pengujian dilakukan dengan membandingkan hasil uji open loop dan close loop dengan variasi temperatur setpoint 40℃,45℃,50℃,55℃, dan 60℃. Adapun nilai error steady-state pada uji close loop dengan input sinyal step untuk temperatur setpoint 40℃,45℃,50℃,55℃ dan 60℃ berturut-turut yaitu 0,0025%, 0,0221%, 0,0262%, 0,0356%, dan 0,0028%. Selain itu nilai settling time juga cukup cepat untuk temperatur setpoint 40℃,45℃,50℃,55℃ dan 60℃ berturut-turut yaitu 12s, 14s, 15s, 17s, dan 17s, dan maximum overshoot dengan nilai yang cukup rendah yaitu 3,24%, 2,56%, 1,9%, 1,26%, dan 0,49%. Sementara itu untuk uji close loop dengan input sinyal drive cycle menghasilkan error rata-rata berturut-turut sebesar 0.817%, 0.983%, 1,321%, 1,748%, dan 2,231%.

Proton Exchange Membrane Fuel Cell (PEMFC) is one of the renewable energy sources that is currently worth considering. In addition to using environmentally friendly fuel, PEMFC can also operate at relatively low temperatures, around 40℃-60℃. To achieve optimal performance of the PEMFC, a control system is required one aspect of which is controlling the stack temperature to remain within the 40℃-60℃ range. In this study, the control system is implemented using a PI controller, with the controlled variable being the stack temperature and the manipulated variable being the coolant flow rate. The modeling is carried out using MATLAB Simulink software. Model validation results show a Root Mean Square Error (RMSE) value of 0.006. Furthermore, testing of the model has been conducted by comparing open-loop and closed-loop test results with variations in setpoint temperature of 40℃,45℃,50℃,55℃, and 60℃. The steady-state error values in the closed-loop test with step input for temperature setpoints of 40℃,45℃,50℃,55℃, and 60℃ are 0.0025%, 0.0221%, 0.0262%, 0.0356%, and 0.0028%, respectively. In addition, the settling times are relatively fast for the temperature setpoints 40℃,45℃,50℃,55℃, and 60℃, at 12s, 14s, 15s, 17s, and 17s, respectively. The maximum overshoot values are also quite low, at 3.24%, 2.56%, 1.9%, 1.26%, and 0.49%. Meanwhile, the closed-loop test with drive cycle input produces average errors of 0.817%, 0.983%, 1.321%, 1.748%, and 2.231%, respectively.
