Kajian Eksergeokonomi ke atas Sistem Sel Bahan Api Membran Elektrolit Polimer

The objective of this study is to perform an exergy and economic analysis on proton electrolyte membrane fuel cell power system (PEMFC) known as exegoeconomic. A 5 kW PEMFC was taken as case study. The fuel cell includes the hydrogen processing system and a fuel cell stack. The hydrogen processing system consisted of an auto-thermal reactor (ATR), a water gas shift reactor (WGS), tubular ceramic membrane module (TCR) and a pressure swing adsorber (PSA). The fuel cell stack was the main power generator. It was obseved that TCM and PSA have low exergy efficiency of 0.29% and 0.09%, repectively. Exergy efficiency for the auto-thermal reactor and fuel cell stack were higher at 22.44% and 31.97%, respectively and both values are comparable with other studies. The exergoeconomics for the 5kW fuel cell system was determined as RM4756.62 per GJ. From the analysis, it is also found that the fuel cell cost can more competative, if the cost of operation, mantainance and fuel can be reduced
