Micro-sized fuel cells

 

The activity was made in the theme "Nanostructures and nanochemistry". We mainly develop hybrid membranes composed of an inorganic skeleton in porous silicon by using cleanroom technology. Inside each Si nanoppore, an organic gel with chemical functions capable to realize the required macroscopic function is grafted on the wall. Then, these new original components are used by partners (CEA) to carry out and test  the properties of micro-sized fuel cells.

We develop infrared spectroscopy as method of characterization. This method is well adapted to the porous silicon because it is transparent in the IR wavelength range. We are able to monitor the amounts of molecules in the pores of the silicon membrane.
