Abstract
Due to high CO2 composition in biogas, hydrogen concentration produced from the biogas reforming process is low, which has negative effect on the SOFC efficiency. Therefore, aims of this study are to improve and analyze the performance of solid oxide fuel cell (SOFC) integrated with hydrogen production from tri-reforming process of biogas coupling to hydrogen-selective membrane separator. The simulation results show that the increase of pressure increases the hydrogen separation in Pd/Ag membrane separator. The Pd/Ag membrane separator can separate hydrogen of 47.5 %, at 8 bar. When comparing the integrated system of SOFC and biogas tri-reforming without/with installing hydrogen-selective membrane separator, the efficiency of system with coupling to hydrogen-selective membrane separator is higher than that without coupling to hydrogen-selective membrane separator about 13-14.7 %.
