Abstract

Studi ini merupakan hasil kegiatan dalam analisa pengembangan sebuah alternative sumber energy terbarukan teknologi hydrogen yang dinamakan sel tunam membrane pertukaran proton (PEM Fuel Cell), melalui analisa pemodelan transport massa pada domain komputasi 2 dimensi dari kanal gas, pelat bipolar, lapisan difusi dan membrane pada kedua electrode. Beberapa hasil akan disampaikan melalui parameter post processing; kontur, vektor yang ada di dalam tools, berupa distribusi spesies reaktan (hydrogen, oksigen dan humidity H2O) ataupun produk (H2O) di masing-masing electrode (anode dan katode). Selanjutnya data hasil tersebut dikaji berdasarkan teori analisa tentang kinetika reaksi yang terjadi, guna diperoleh factor utama yang mempengaruhi kinerja densitas arus yang dihasilkan. Dari hasil simulasi pada parameter optimum operasi dan desain yaitu sebesar tekanan statis 15 psi.g, temperature saturasi air 70 oC, tegangan listrik 0,6 volt, porositas lapisan difusi 0,4, porositas lapisan katalis 0,6 dan kedalaman rib 1 mm, diperoleh nilai optimasi densitas arus katalis anode sebesar 10750 A/m2. Kata kunci: densitas arus, parameter desain dan operasi, domain, PEMFC, spesies.

Abstract

The study of bio-micro high power density power generation system simulations for Zero Energy Building (ZEB) has been done, by analyzing the improvement momentum parameters for rotating impulse power turbines refers to the potential local bio-renewable energy sources. The main improvement parameters which are velocity and mass flow, would be analyzed in dynamic simulations of the thermal power generation system to give the estimated fuel rate requirement for appropriate heat enthalpy and predicted output power. Input parameters of simulation such as pressure, temperature, mass flow determined as design points of thermodynamics cycle. Using the fuel rate range 0.1 - 1 kg/s, LHV 12000 kJ/kg, and steam temperature from 120-165 oC, could predict the output power more than 300 kW. For power turbine demand range from 100 - 300 kW, it requires fuel rate 0.5-1 kg/s (LHV=12000 kJ/kg) and saturated steam pressure 360-700 kPa. This simulation model could give the conceptual design of thermal power generation for ZEB.
