چکیده
Entering a new era of sustainable energy generation and consumption, micro-fuel cells are showing great potential for providing high density to consumer electronics, micro-reactor technology can indeed enable their integration by hydrogen on-demand from hydrocarbons. In this work, we present the design fully scalable wafer-level fabrication MEMS-based catalytic tested in real-life operating conditions means 3D printed ceramic housing. The device consists an array thousands vertically aligned micro-channels, 500 ?m length 50 diameter, overall superficial area per unit volume 120 cm2 cm?3 it embeds thin-film heater efficient reaction start-up. For first time, functionalization is entirely achieved atomic layer deposition (ALD) rapid thermal processing (RTP), resulting uniform coating Pt/Al2O3 heterogeneous catalyst hereby steam reforming (SR) partial oxidation (POX) dimethyl ether (DME). Here, conversion rates up 74% selectivity ~60% obtained at 650 °C, while specific volumetric production 4.5 mLH2 mL?1DME cm?3REACTOR 600 °C DME POX.

متن کاملFeasibility of Hydrogen Production from Micro Hydropower Projects in Nepal
The current energy crisis in Nepal clearly indicates that the future energy-demand cannot be met by traditional energy-sources. Community-based micro-hydropower operations are considered to be one of the most feasible options for energy development. However, the power plant capacity factor remains very low due to limited commercial and business opportunities. Generation of hydrogen (H2) from th...
