Research Abstract

This work aimed designing and arrangements of fuel cell electrodes through nanotechnology in order to develop advanced fuel cell systems. Experiments using miucrofabrication technique and electrochemistry as well as simulation using a multiphysics software were performed. Finally, fundamental technique for fabricating devices based on nanoporous materials was successfully developed, which enable developments of two-dimensional nano-devices.
