 Solid oxide fuel cells (SOFCs) efficiently convert chemical energy directly into electricity, with only water as product. They are typically built in large scale and for stationary applications, due to the high operating temperature (600 to 1000 °C), therefore their applications are difficult for small scale power sources. However, SOFCs bear inherent advantages over current room temperature fuel cells, and recently several efforts have succeeded on reducing the operating temperature, either with thinner electrolyte or enhancement of catalyst/electrolyte interfaces. In particular, thin film electrolyte significantly reduces the Ohmic resistance of SOFCs and allows low temperature operations (250 to 400 °C). This talk will introduce a high-power density low temperature solid oxide fuel cells fabricated by means of micro- and nano-fabrication processes and atomic layer deposition (ALD).

 Dr. Yong-Jin Yoon joined School of Mechanical & Aerospace Engineering at Nanyang Technological University (NTU) as an Assistant Professor in January, 2010. He obtained his Ph.D. degree in the Mechanical Engineering at Stanford University in September 2009. During his PhD study, he also obtained two Master degrees in Stanford: one in Electrical Engineering, focusing on MEMS and Signal Processing, and the other in Mechanical Engineering, focusing on Medical Device Design. He was the co-founder of one internet solution company and one online game company in South Korea back in year 2000.
During his doctoral study in Stanford, he worked in OtoBiomechanics Group in the fields of hearing mechanics. He worked closely with Stanford Medical School Otolaryngology Department for Head, Neck Surgery, focusing on inner- and middle-ear biomechanics, auditory technologies, surgical simulations, μCT and MR imaging. Currently, his researches at NTU include biomimetic electroacoustic MEMS transducer, psychoacoustic neuroscience, bio-chemical MEMS sensor, medical device, fuel cell, and surgical simulation.
