SUMMARY:Portable Direct Methanol Fuel Cell System for Green Computing
DESCRIPTION:Portable Direct Methanol Fuel Cell System for Green Computing\n\n\n\n\nSpeaker\n\n\nDr. Naehyuck Chang\nSeoul National University\n\n\n\n\n\n\n\n\n\n\nCECS Host\n\n\nProfessor Pai Chou\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nCalIT2 Room 3008\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nAugust 5 \, 2009\nRefreshments at 10:00 am\, Lecture begins at 10:30am\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nWe introduce a hybrid portable direct methanol fuel cell (DMFC) system\nwhich includes a li-ion battery. We demonstrate a hybrid operation of\nthe DMFC stack and the li-ion battery to maintain a constant stack\noutput current regardless of the load current to maximize the\nperformance. We describe the balance of plant (BOP) control system\,\nincluding a 32-bit microprocessor\, and electronics to drive motors\,\nactuators and sensors for reliable operation and protection of a DMFC\nsystem. The dynamics of BOP control is taken into account to design\nmultiple cascaded feedback control loops. We demonstrate robust\noperation of a DMFC system together with introduction of a DMFC system\ndesign. This talk includes a working prototype system demonstration of a\ncomplete DMFC and battery hybrid power source.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n\n \nNaehyuck Chang received his BS\, MS and PhD degrees all from Seoul National University\, in 1989\, 1992 and 1996\, respectively. He was a research associate at Dept. of Electrical Engineering and Computer Science at University of Michigan in Ann Arbor in 1997. He joined Seoul National University in Dept. of Computer Science and Engineering in 1997 as a faculty member and now is an Associate Professor in Dept. of Electrical Engineering and Computer Science. He was also a Visiting Associate Professor at Arizona State University in 2005. He has been with Sindoricoh\, Co. Ltd.\, as a Technical Advisor since 2001. He has published more than 70 technical papers in low-power and embedded systems area.
