DMFC uses oxygen by reactants. Therefore, cathode electrode must contact with outside air. However, when used in mobile devices, the user's body by blocking the air intake on the oxygen supply DMFC con not. DMFC to supply air to the cooling fan is used. However, by using cooling fan, air inlet to the pressure loss and changes will occurs, the output will be worse. In this paper, we designed air supplying system using piezo actuators. We DMFC evaluation system was implemented, verified the performance of air supplying system. And the operation was connected to an MP3 player.
