Abstract

Perkembangan kendaraan ramah lingkungan mendorong pemanfaatan proton exchange membrane fuel cell (PEMFC) sebagai sumber energi alternatif pada sektor transportasi. Salah satu konfigurasi PEMFC adalah sistem resirkulasi anoda pasif yang menggunakan ejektor untuk meresirkulasikan hidrogen yang tidak terpakai untuk masuk lagi ke inlet anoda. Konfigurasi ini menghadapi tantangan berupa penurunan tekanan pada anoda inlet yang dapat menurunkan performa fuel cell. Penelitian ini bertujuan untuk merancang sistem kontrol tekanan inlet anoda pada PEMFC resirkulasi pasif menggunakan metode kontrol proportional-integral (PI) dengan
gain scheduling berdasarkan variasi arus beban. Pengujian dilakukan pada PEMFC Horizon 500 dengan rentang arus 1–10 A, menggunakan mass flow controller berbasis proportional solenoid valve sebagai aktuator. Perancangan sistem kontrol berbasis PI gain scheduling dilakukan secara eksperimental. Hasil menunjukkan bahwa penerapan kontrol PI dengan gain yang disesuaikan secara otomatis terhadap perubahan arus beban mampu menjaga tekanan inlet tetap stabil dan meningkatkan efisiensi PEMFC maksimum sebesar 2,63% dibandingkan konfigurasi resirkulasi pasif tanpa kontrol tekanan inlet anoda dan 6,16% dibandingkan konfigurasi dead ended.

The development of environmentally friendly vehicles has encouraged the use of Proton Exchange Membrane Fuel Cells (PEMFC) as an alternative energy source in the transportation sector. One configuration of PEMFC is the passive anode recirculation system, which uses an ejector to recirculate unused hydrogen back to the anode inlet. This configuration faces challenges such as a drop in anode inlet pressure, which can reduce fuel cell performance. This study aims to design an anode inlet pressure control system for passively recirculated PEMFC using a proportional-integral (PI) control method with gain scheduling based on load current variations. The experiment was conducted on a Horizon 500 PEMFC with a current range of 1–10 A, using a mass flow controller based on a proportional solenoid valve as the actuator. The PI gain scheduling-based control system was designed experimentally. The results show that the application of PI control with automatically adjusted gains according to changes in load current can maintain stable inlet pressure and improve maximum PEMFC efficiency by 2.63% compared to the passive recirculation configuration without inlet pressure control, and by 6.16% compared to the dead-ended configuration.
