碩士 === 國立臺北科技大學 === 材料科學與工程研究所 === 99 === The solid oxide fuel cell (SOFC) has the highest efficiency and the most compatibility among the various fuel cells. This project used anode support solid oxide fuel cells, utilized ceramic as the anode, electrolyte and cathode.(call a positive electrode, electrolyte-negative electrode, PEN) Each unit planar cell consists basically of a PEN, assembly, interconnector, porous nickel and ceramic seals. In this study used big-size(106mm ×106mm ×0.72mm) planar anode support PEN, and used the fuel gas(H2+3% H2O), cathode used air, when measuring the maximum power densities~107 mW/cm2 at 500℃,and ~193mW/ cm2 at 550℃,and ~307mW/ cm2 at 600℃. the voltage-current density polarization curves (PC) show a reasonable value.
