Fuel Cells are energy conversion devices which convert chemical energy
of fuel into electric energy directly. They are more efficient compared to
combustion engines. Also, undesirable products such as NOx and Sox are
virtually zero.

 LTFCs (Low Temperature Fuel Cell), PEMFC and DMFC, have high energy density so they are suitable for portable device and transportation. However, limited resources and high cost of Pt in electrodes hinder the widespread commercialization of fuel cells. Further, the high cost of membrane and low oxidation rate of methanol remained as technical drawbacks.

We focus on the development of composite membrane to substitute for Nafion membrane using 
inorganic filler and carbon. In electrodes case, we investigate tungsten carbide for anode catalysts, nitrogen treated carbon and nitride materials for cathode catalysts to make low-Pt or non-Pt electro-catalysts.

- Synthesis of noble-metal-thrifty electro-catalysts for electrochemical oxidation of ethanol and hydrogen.

- Development of Inorganic Fillers for Polymer Composite Membranes for DMFC.

- Research for cathodic catalysts preserved the high corrosion resistance on carbon materials.

- Direct methylformate fuel cell.
