[Key Technology]
The cell and stack is a critical issue for further integrating component development. In addition to standard single cell (adopted as standard testing cell by well-known test equipment manufacturer-CHINO ) developed jointly with micro power fuel cell Co., Ltd, two types of stack design with different air inlet are developed successfully using commercial membrane electrode assemblies (MEAs). A short stack includes conventional fuel and air inlet with parallel flow direction. The cooling system was built in with external cooling water. This short stack composed of 4 cells with active area of 100 cm2 has maximum power density of 0.55 W/cm2 and peak power of 250 W. In addition, development of a 8-cell stack with air-breathing cathode using small pump is under progress. The structure is suitable for bicycle application with direct air inlet. With the air acting as a cooling medium, the maximum power density of 0.20 W/cm2 was obtained at lower temperature arround 40℃. In addition to stack design with hydrogen fuel, FCC is actively engaged in the development of compact direct methanol fuel cells (DMFCs) stack for portable power applications.

[Research Target]
.Establish stack failure mode and lower degradation rate to 25μA/hr
.Develop modular cell technology and lower power generation cost upto USD $17/W
