solid oxide fuel cell with sugar cube size
National Institute of Industrial Science and Technology in Japanadapter for laptop developed a work under conditions at 550 ℃, the volume very small SOFC (solid oxide fuel cells). By cylindrical cell size significantly reduced with the volume increase corresponding to the electrode area ratio. Size is small, but the fuel cell output power is indeed very high. Set of 25 can be prepared to do a diameter of 0.8mm of the needle-like modules in one, sugar size, with a 3W power-generating capacity of SOFC.
In addition, but also to its integration in the form of the initial integration, and per square centimeter to set more than 250 units (Figure 2). Except for combined heat and power systems (Cogeneration), he also strive to be used in vehicles APU (auxiliary power unit). Will be in February 2009 18 to 20 at Tokyo Big Sight International Convention and Exhibition Center held “nano tech 2009 International Nanotechnology Integrated Exhibition” NEDO booth display.
In the fuel cell, SOFC are more efficient, so electricity use is expected mainly in the application of combined heat and power systems. However, due to higher operating temperature for the 700 ~ 1000 ℃, load changes so poor, in the automotive field, the better PEFC (Polymer Electrolyte Fuel Cell). Smaller prototype module, the heat capacity is small, low operating temperature. Small in absolute terms due to thermal expansion and therefore less thermal shock can sony laptop batterybe realized fast start. Prior has been a period of about five minutes start, but the middle class & Research Institute of Advanced Manufacturing Technology Research Group research function modules Masanobu Awano, head of the view that this “can be realized in seconds of the start.”
At present, the car uses, it is envisaged for the load changes in a smaller APU, but if establishing an effective technology to connect multiple modules, it can also power the fuel cell vehicle the application.
