چکیده

A high surface area and micro process integrated cathode for μ-DMFC is introduced in this study. CNTs growth inside micro structured cathode for catalyst support was employed for reaction surface increment, while liquid Nafion spun into radial arranged micro reaction holes controlled by centrifugal force was carried out to provide proper immersion ratio of CNTs in Nafion. The process is all integrated by MEMS process and the device is expected to improve proton transport and oxygen reaction efficiency over traditional carbon cloth based DMFC systems.

Design of a New Micro Direct Methanol Fuel Cell Using MEMS Technology

In this paper, a special micro DMFC using MEMS technology is designed to work in a circumrotating condition, which providing power using inertia over-load. The designed cell is a cylinder, anode channel is inside, cathode is outside and exposes to the air. When the overload exceeds the critical value, the liquid inside reserve tank will splash and comes into the two electrodes, and then the cel...

MTL Annual Research Report 2004-2005

We have developed a novel method of manufacturing and assembling process termed nano-pelleting [1-2], which refers to large-scale handling and long-range order assembly of individual carbon nanotubes (CNTs). The nano-pelleting concept overcomes the limitation of very small-scale order by embedding carbon nanotubes into micro-scale pellets. This technique includes vertically growing single stran...

Improved performance of micro-fabricated preconcentrators using silica nanoparticles as a surface template.

A new approach of enhancing the adsorption capability of the widely used polymer adsorbent Tenax TA poly(2,6-diphenylene oxide) through its deposition on a nano-structured template is reported. The modified Tenax TA-coated silica nanoparticles (SNP) are incorporated as an adsorbent bed in silicon based micro-thermal preconcentrator (μTPC) chips with an array of square microposts embedded inside...
