Nissan Motor Co. Ltd. prototyped an SOFC (solid oxide fuel cell) and exhibited it at the International Nanotechnology Exhibition and Conference (Nano Tech 2009), which is taking place at Tokyo Big Site from Feb. 18 to 20, 2009.

The company plans to mount the SOFC on an electric vehicle and use it to charge the battery of the vehicle in the future.

SOFCs are highly efficient but have problems starting up. Therefore, they have been believed to be appropriate for cogeneration but not so much so for automobiles. And PEFCs (polymer electrolyte fuel cell) have been the leading candidates for automotive fuel cells.
