A low-voltage micropump with no moving parts and based on standard MEMS fabrication techniques has been developed. The pump has been characterized by pumping a variety of liquids, including de-ionized water, phosphate buffer saline, and aqueous solutions of sugars and alcohols as well as pure methanol, with typical pumping speeds of a few hundred micrometer per second. The small power/voltage r...

Based on the incompressible Navier Stokes equation (N-S) and coupling principle of laminar flow electric field, a new 3D electroosmotic micromixer with variable module is designed in this paper. A microchannel throughout to improve mixing efficiency. The efficiency different directions, positions, alternating voltages times was studied. It can be seen from simulation results that under influenc...

New bi-layer PFSA membranes made of Nafion® NRE212 and Aquivion™ E79-05s with different equivalent weights are prepared with the aim of managing water repartition in the PEMFC. The membrane water transport properties, i.e. back-diffusion and electroosmosis, as well as the electrochemical performances, are compared to those of state-of-art materials. The actual water content (the inner water con...
