SEQUENTIAL POWER GENERATION FOR PLOLONGING THE NET LIFETIME OF A MINIATURE BIOFUEL CELL STACK

We have developed a sequential power generation system, in which each of stacked enzyme fuel cells was designed to be exposed sequentially to fuel solution by automatically switched fuel flow. The time when the cover was opened by attraction with an external magnet, thereby activating the following cell, was adjustable from a few hours to a few weeks by controlling the weight ratio of Fe3O4 in the covers and the molecular weight of PLGA. By using sequential power generation in this way, the net lifetime of the stack has been extended as compared with that of a single biofuel cell.
