Abstract

A fuel cell power generation system is a renewable energy system that works based on electrochemical processes and produces a direct electric current (DC). Specifically, a Proton Exchange Membrane (PEM) Fuel Cell can operate at low temperatures and produce an efficiency of around 40-60%. In this study, the performance test of the PEM Fuel Cell for power generation was carried out by supplying hydrogen gas using hydrogen from the electrolysis of the hydrogen generator with a variation of KOH catalyst solution with a concentration of 0.5 M; 1.0 M; 1.5 M; 2 M and using Ultra High Purity (UHP) hydrogen with various flow rates of 250 mL/min, 300 mL/min, 350 mL/min, 400 mL/min, 450 mL/min, and 500 mL/min. The test results showed that the output power of hydrogen produced by the electrolysis process was 10.8 W at a concentration of 1 M solutions at an input current of 20 A. The greater the concentration of the catalyst solution, the smaller the electrical power required for the electrolysis process. However, the hydrogen power supply produced by the hydrogen generator was not optimal, so it did not meet the needs of the PEM Fuel Cell. As a result, the PEM Fuel Cell could not work. Meanwhile, testing with UHP hydrogen produced the highest electrical power of 31.588 W at a flow rate of 450 mL/min with a load of 20 W. It indicates that the PEM Fuel Cell is optimal at the output power value with an efficiency of 69.80%.

Abstract

Keterbatasan akses informasi akibat infrastruktur yang belum memadai di beberapa daerah berpotensi menutup ruang keterlibatan masyarakat di dalam proses pembangunan. Hal ini menjadi penyebab sering terjadinya kegagalan dalam mencapai target pembangunan yang inklusif dan berkelanjutan. Kegiatan ini bertujuan untuk memastikan keterbatasan akses informasi masyarakat tersebut dapat diatasi melalui desiminasi teknologi papan informasi berbasis solar PV mulai dari sistem pemerintahan terbawah, yaitu desa. Aparatur Desa Surokonto Wetan dilibatkan sebagai mitra di dalam kegiatan ini. Pendekatan Participatory Rural Appraisal (PRA) digunakan di semua tahapan proses. Kegiatan ini menghasilkan seperangkat teknologi sistem informasi yang dapat diakses masyarakat secara luas untuk mendapatkan informasi sistem pemerintahan yang transparan.
