Planar micro-direct methanol fuel cell prototyped by rapid powder blasting

Martinus Adela Maria Gijs, Meng Shen

We present a planar micro-direct methanol fuel cell (μ−DMFC) fabricated by rapid prototyping powder blasting technology. Using an elastomeric mask, we pattern two parallel microfluidic channels in glass. The anode and cathode of the fuel cell are formed by ...

Fabrication of microfluidic mixers with varying topography in glass using the powder blasting process

Martinus Adela Maria Gijs, Virendra Kumar Parashar, Abdeljalil Sayah

The powder-blasting method is used to fabricate structures with a three-dimensional topography in glass using elastomeric masks. The relation between the mask opening width and the erosion depth is exploited to fabricate microstructures with varying depth ...
