Abstract

Fuel Cell merupakan suatu sumber energi ramah lingkungan yang mereaksikan hidrogen pada anoda dan oksigen pada katoda. Dengan proses elektrokimia fuel cell dapat menghasilkan keluaran berupa energi listrik dan produk samping. Terdapat banyak cara untuk meningkatkan performansi fuel cell salah satunya dengan menjaga temperatur operasinya pada temperatur optimal. Sebelum membuat kontrol tersebut dibutuhkan suatu rancang bangun monitoring temperatur untuk dapat mengetahui karakteristik dari fuel cell. Fuel cell yang digunakan pada penelitian tugas akhir ini berjenis proton exchange membran fuel cell (PEMFC) dengan konfigurasi open cathode yang memiliki kapasitas nominal 5kW. Hasil dari sistem monitoring temperatur yang dibuat pada PEMFC single-stack 5kW mempunyai keandalan dan kinerja yang sangat baik karena memiliki nilai error sangat kecil, nilai akurasi yang hampir sempurna dan presisi yang konsisten. Error dengan nilai 0,76% menunjukkan nilai error pengukuran temperatur sangat kecil. Akurasi pengukuran sebesar 99,459%, menunjukkan bahwa sistem monitoring ini hampir 100% tepat dalam pengukuran. Presisi sistem sebesar 99,461% menunjukkan konsistensi yang baik dari hasil pengukuran berulang sistem. Karakteristik temperatur dengan variasi beban (15A, 30A, 45A, 60A, 80A) pada PEMFC menunjukkan bahwa peningkatan beban listrik yang diberikan pada sistem secara langsung berkorelasi dengan peningkatan temperatur operasi dalam PEMFC.

Fuel Cell is an environmentally friendly energy source that reacts hydrogen at the anode and oxygen at the cathode. With the electrochemical process of fuel cells can produce output in the form of electrical energy and by-products. There are many ways to improve fuel cell performance, one of which is by maintaining its operating temperature at the optimum temperature. Before making the control, a temperature monitoring design is needed to be able to know the characteristics of the fuel cell. The fuel cell used in this final project research is a type of proton exchange membrane fuel cell (PEMFC) with an open cathode configuration that has a nominal capacity of 5kW. The results of the temperature monitoring system made on the 5kW single-stack PEMFC have excellent reliability and performance because it has a very small error value, almost perfect accuracy value and consistent precision. Error with a value of 0.76% indicates a very small temperature measurement error value. Measurement accuracy of 99.459%, indicating that this monitoring system is almost 100% correct in measurement. The system precision of 99.461% shows the good consistency of the system's repeated measurement results. Temperature characteristics with load variations (15A, 30A, 45A, 60A, 80A) in PEMFC show that an increase in the electrical load applied to the system directly correlates with an increase in operating temperature in PEMFC.
