Fuel Cells & Electrochemical Sensors
The direct-methanol fuel cells & hydrogen fuel cells have been fabricated and characterized for portable application. The electro-chemical sensors are also developed using nano-materials such as nanotubes, nanowires, and nanofoams. They are of benefit in the area of electro-chemical energy storage and electrochemical sensors for gases and bio-materials detection.

Nano-electrodes & Energy devices
(Super-capacitors / Li-ion batteries / Solar cells) We have manufactured nano-electrodes of metals or metal-oxides, on which the nano-particles and bump-typed or needle-shaped dendrite structures exist. These extremely high surface area nano-porous electrodes have been fabricated by the unique electroplating process on dynamic hydrogen-bubble template or the spontaneous galvanic displacement reactions. Using these nano-electrodes, we have developed the energy devices such as supercapacitors, Li-ion batteries, and solar cells for the next-generation energy storage and conversion system.

Fundamental study on electrochemical reaction mechanism
The surface reaction mechanisms of electrochemical processes are investigated using in-situ Fourier-transform infrared spectroscopy and other electrochemical analyses. The electro-chemical reaction are characterized and optimized by monitoring the behaviour of electrodes and electrolytes in electroplating, fuel cells, super-capacitors, metal ion batteries, and other energy devices.
