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 penambahan humidifier. Fuel cell yang digunakan pada eksperimen ini berjenis proton exchange membrane fuel cell (PEMFC) dengan konfigurasi open cathode dengan tipe G-HFCS-1kW36V yang memiliki kapasitas nominal 1kW. Penambahan humidifier dilakukan pada anoda dengan menjaga nilai relative humidity berkisar 70% - 80%. Komponen yang digunakan dalam penambahan sistem humidifikasi ini yaitu bubble humidifier, sensor kelembapan, dan solenoid valve. Sistem pengendali on-off digunakan pada eksperimen ini, dimana bacaan sensor kelembapan akan mendasari pemilihan pembukaan solenoid valve. Sistem kontrol ini memiliki nilai overshoot sebesar 2,86%, undershoot sebesar 3,89%, dan deadband sebesar 10,00%. Penambahan humidifier memperbaiki performansi fuel cell. Daya keluaran meningkat maksimal sebesar 23,00%, efisiensi stack meningkat maksimal sebesar 0,22%, efisiensi reduksi hidrogen meningkat maksimal sebesar 3,40%. Semua peningkatan maksimal terjadi dengan pemberian arus beban 6A. =============================================================================================================================
Fuel cell is an environmentally friendly energy source that reacts hydrogen at the anode and oxygen at the cathode. With an elektrokimia process, the fuel cell can produce output in the form of electrical energy and side products. There are many ways to improve fuel cell performance, one of which is by adding a humidifier. The fuel cell used in this experiment is a proton exchange membran fuel cell (PEMFC) with an open cathode configuration of type G-HFCS-1kW36V which has a nominal capacity of 1kW. The addition of a humidifier is carried out at the anode by maintaining a relative humidity value of around 70% - 80%. The components used in the addition of this humidification system are bubble humidifiers, humidity sensors, and solenoid valves. An on-off control system is used in this experiment, where the humidity sensor reading will be the basis for selecting the opening of the solenoid valve. This control system has an overshoot value of 2.86%, an undershoot of 3.89%, and a deadband of 10%. The addition of a humidifier improves fuel cell performance. The maximum output power increases by 23%, the stack efficiency increases by a maximum of 0.22%, the hydrogen efficiency increases by a maximum of 3.40%. All the maximum increases occur with the supply of 6A load current.
