Abstract

$WSUHVHQWWKHPDMRULW\RIWKHZRUOG¶VHQHUJ\LVSURGXFHGIURPIRVVLOIXHOVVXFKDVcoal, oil and natural gas, but alternative, environmentally sustainable energy sources are under active investigation. Among these sources, PLFURELDO IXHO FHOOV DSSHDU WR RIIHU PXFK SURPLVH LQ VXSSRUW RI WKH XOWLPDWH JRDO RI ³FDUERQ QHXWUDO´ ELRPDVV energy production for a sustainable society. Due to their excellent electrical characteristics, the application of carbon nanotube technology (CNT) to these fuel cells has been investigated, with the goal of improving the overall power generation efficiency. In addition, the possibility of employing microbial fuel cells for biomass hydrogen production was also studied, and results from both the power generation and biomass hydrogen production studies are reported.
